Washington: The man police say shot and killed six people in Michigan last month has told officers he was being controlled by the Uber app on his phone when the shooting spree occurred.

When a police officer asked Uber driver Jason Brian Dalton about the Kalamazoo shooting, he told them that when he opened the app, a symbol appeared that "would literally take over your whole body," an officer wrote in a police report released on Monday.

During an interview with detectives, Dalton said he did not remember shooting people, though he acknowledged that the families of people killed deserved an explanation for what happened. After talking with the detectives for some time, Dalton was asked for an explanation and said that the reason "would blow [their] minds," Detective William Moorian of the Kalamazoo Department of Public Safety wrote in his report on the interview.

"Dalton said that he understands now how the other mass shootings take place," Mr Moorian wrote. "Dalton explained how he has experienced a full body takeover, that is how he can understand the other mass shootings."
