PV International Desk : British police named the man who stabbed two people to death in London on Friday in what the authorities called a terrorist attack as 28-year-old Usman Khan, who had been convicted of terrorism offences and was released from prison last year.

“This individual was known to authorities, having been convicted in 2012 for terrorism offences,” Britain’s top counter-terrorism police officer, Neil Basu, said in a statement.

“He was released from prison in December 2018 on licence and clearly, a key line of enquiry now is to establish how he came to carry out this attack,” Basu said.

A person who is released on licence is subject to conditions for the duration of their sentence after leaving prison. The Times newspaper reported that Khan had agreed to wear an electronic tag.
