Walmart is coming under fire following a recent incident in Tuscon, Arizona where a thief was able to shoot of rounds from a weapon after stealing it from their store. Mario Valencia took a rifle from the super store on February 19 and was able to start firing it as soon as he left, something that should have been impossible due to the gun locks that are required on all weapons. This after he demanded bullets from a woman inside the store guarding the ammunition case, who did as instructed and then immediately notified authorities. Scroll down for video . Mario Valencia (above) took a rifle from a Walmart in Tuscon, Arizona on February 19 and was able to start firing it as soon as he left . The stolen weapon should have still been locked and police chasing the men were told he could not fire the loaded gun . Police were even told the gun was locked by employees at the store as they pursued Valencia, but just seconds later he began firing into the air according to CNN. He even pointed the weapon at an officer at one point. When the gun was later recovered, after Valencia was taken down by Officer Michael Rapiejko, it was discovered the wire was loose, and only wrapped through the gun's barrel and lock just once, not twice as is standard, allowing the weapon to be used as soon as it was taken. Walmart meanwhile claims the rifle had been properly locked, and that it may have been affected by the hard blow caused by the police car . He was later taken out by an officer who hit him with his vehicle . The gun was found to be locked with loose wire that was not wrapped enough when police recovered it from the scene . Video of the incident, which emerged last week, shows Rapiejko, 34, running into  Valencia to take the man down after he began firing the weapom. A police officer in one of the patrol cars says: 'One round just went out. He's definitely loaded.' He then tells his colleague, Rapiejko, in the other vehicle: 'Stand off, the gun is loaded.' Valencia is facing several felony charges for his alleged crime spree . But apparently ignoring his advice, Rapiejko overtakes the officer's car, before speeding straight toward Valencia. Seconds later, his vehicle mounts the curb and smashes into the suspect's body. Valencia is sent flying into the air, while the car crashes through a concrete wall before coming to a halt amid debris. The other officer can be heard shouting in shock: 'Oh! Jesus Christ, man down.' Valencia was rushed to University of Arizona Medical Center in serious condition following the crash and was eventually booked into jail two days later. Sergeant Chris Warren said at the time that Valencia 'was a dangerous felon who'd been on a crime spree throughout the morning'. This crime spree allegedly involved theft at a convenience store at, vandalism and burglary at the Tucson Baptist Temple, a home invasion and theft of a car. It culminated with the alleged theft of a rifle from Walmart, after which he was hit by Rapiejko's police vehicle. Rapiejko was put on standard administrative leave after the crash, but soon reinstated after the Pima County Attorney's Office cleared the officer of any wrongdoing. Valencia is facing several felony charges for his alleged crime spree.
