NASHVILLE, Tenn. (WZTV) - What started out as Halloween fun for a group of friends in Nashville turned into real horror when a woman says she was approached by someone and unknowingly given a real knife which was used to stab her friend. 
 
 Metro Police are investigating the stabbing that happened Friday night at Nashville Nightmare, a popular Halloween attraction in Madison. At this attraction, people dressed up in Halloween costumes roam the grounds, interacting with guests and working carnival-type games. 
 
 According to an incident report from Metro Police, officers were told that a group of four friends had gone to Nashville Nightmare and while inside the venue area, they were approached by someone whom they thought was a character there. Nashville Nightmare says they also believe the person involved was an employee, who has since been placed on leave. 
 
 FOX 17 News spoke with the woman Tawnya Greenfield, who says the group had already gone inside the haunted houses and was playing carnival-type games when it happened inside the roped off area. 
 
 The possible employee, dressed and talking in character, Greenfield if the victim, a friend of Greenfield's, was messing around with her. Playing along with whom she thought to be a character from the attraction she said "yes." The unknown person then handed Greenfield a knife, which she thought was a prop knife. The person, speaking in character according to Greenfield, then said, “well here, stab him.” 
 
 Police said Greenfield, only playing along and believing the knife was a prop, stabbed the victim. Greenfield told us she even joked saying, "ha,ha gotcha!" 
 
 But when Greenfield pulled back, she realized the terrifying truth. 
 
 "His arm was gushing blood like something out of a horror scene," Greenfield said. 
 
 There was blood on the knife, a hole in the victim’s shirt and “blood squirting from the victim’s left arm.” Greenfield told police, and FOX 17 News, she didn’t mean to hurt the victim. Medics responded to the Nashville Nightmare and transported the victim to be treated for his injuries at Skyline Hospital. 
 
 
 
 Greenfield says the unknown person, a man, ran away after the incident. 
 
 Two others were in the group with the woman and victim, who corroborate the story about the prop knife. 
 
 The person who walked up to the group is now believed to be an employee, but Nashville Nightmare is investigating and the group involved in the real horror story is seeking legal action. 
 
 Official statement from Nashville Nightmare: 
 
 The safety and security of our patrons is our top priority, and, for the past 8 years, we have hosted Nashville Nightmare without any security incidents or major injuries. 
 
 We are still confirming the facts, but I can tell you that on Friday night, a male patron was injured by a fellow patron outside the Nashville Nightmare house. Our medical staff responded immediately, and the injured party was transported to the hospital where we understand that he was treated and released.

We have not been contacted by the police, but we will cooperate fully with any official investigation. ||||| It was supposed to be a fun outing to a haunted house with friends until a man, believed to be one of the house's actors — a thin man with a skull face — walked up to them and handed one of them a knife. 
 
 The group of friends at the Nashville haunted house last Friday night decided to play along, so when the thin figure with a straw hat asked one of the women if one of her friends was "fucking around with her," she said yes. 
 
 "Well, here, stab him," he said, handing her a knife, according to the police report obtained by BuzzFeed News. 
 
 The 29-year-old woman took the knife, which she thought was fake, and plunged it into her friend's left arm. 
 
 "As she pulled back she realized that there was blood on the knife," the report states. "There was a hole in the victim's shirt and blood was squirting from the victim's left arm." 
 
 Her friend, 29-year-old James Yochim, was taken to a nearby hospital to be treated for his injuries.
– Halloween is James Yochim's favorite time of year: "I get really excited about going to haunted houses." His Friday night at Nashville Nightmare in Madison—a sprawling attraction with four haunted houses, an escape room, and scary cast members running around with fake weapons—might dull the thrill, however. Yochim says a thin man with skull makeup, assumed to be an actor, approached his friend, Tawnya Greenfield, asking if Yochim was "f—ing around with her," per BuzzFeed. When she jokingly said yes, the man handed her a knife and said "stab him," Yochim tells the Nashville Tennessean. "Keep in mind, we'd been chased by chainsaws, holding other weapons, all kinds of stuff all night, and it was all fake," he adds. "So she stabs at me with it, and everything got really black." The blade—very much real—went through the 29-year-old's forearm. Though it didn't hit any major arteries, bones, or tendons, "his arm was gushing blood like something out of a horror scene," Greenfield tells Fox 17. Nine stitches later, Yochim recalls the unknown man apologizing as he lay bleeding, saying, "I didn't know my knife was that sharp." But according to Yochim, there were no weapons allowed inside the attraction and visitors were required to go through "very thorough" metal detectors. In a Tuesday statement, Nashville Nightmare's organizers said an employee believed to be "involved in some way" had been placed on leave "until we can determine his involvement." An initial police report said the suspect had not been identified. No charges have been laid.
