A 10-year-old boy climbed through a school window and jumped to his death after his chess opponent failed to say 'checkmate' after beating him, a police report has revealed. The child, whose name has not been released, suffered fatal injuries in the incident at Grant Elementary School in Dumont, New Jersey on March 6 and died later that day. On Wednesday, police released a report after an investigation into his death, The Record reported. The fifth-grader had been playing chess with another student during a morning recess period when he became upset that his opponent didn't say 'checkmate', according to the report. An aide overheard him saying to the other student: 'Do you want me to do something drastic?' Tragic: A 10-year-old boy jumped to his death from a window at Grant Elementary School in New Jersey last month after becoming upset following a losing chess match, according to a new police report . She told police that as the students were about to leave the room for lunch, she saw him crying in a corner and writing a note, which he passed to his opponent but told him not to open it until later. She confiscated the note and when she turned around to look at the boy, she saw him climbing through a window before jumping through the second-story window, the report said. He had managed to lift himself onto shelves and had crawled along the top towards the window, which was open about a foot, according to witness statements. He went through the window 'headfirst, unforced, unassisted and of his own accord' and suffered 'serious facial injuries', the report said. Witnesses said the boy seemed to be conscious and moving after hitting the ground but he died in the hospital several hours later, The Record previously reported. The contents of the note he passed to his classmate have not been disclosed. After the tragedy, the classmate said the boy had made references to jumping out the window on four previous occasions - but he didn't tell anyone because he didn't think the boy was serious. After losing another chess match in December, the boy got angry and said, 'I'm this close to jumping out the window!' while holding his thumb and index finger about an inch apart, the classmate said. Upset: The boy had previously told his chess opponent on four separate occasions that he would jump out the window, but the classmate told police he thought the boy was just messing around (stock photo) In the days before he jumped, the boy had also told the lunch aide that no one was letting him play chess with them, so she told the other students to include him. A classmate reported seeing the student often eating lunch on his own. The report concluded that no criminal charges will be brought in the incident. The school has not spoken out about any potential changes to its policies and an attorney for the school declined to comment on Wednesday. But several Dumont High School students said that their school has imposed a new policy that prohibits windows from being opened more than 6 inches, The Record reported. Some of the windows have been fitted with screws that stop them from opening up all the way, the students added. • For confidential help, call the National Suicide Prevention Lifeline at 1-800-273-8255 or click here . • For confidential support on suicide matters in the UK, call the Samaritans on 08457 90 90 90, visit a local Samaritans branch or click here .
