Years before Usman Khan was shot and killed by police after London Bridge stabbing, authorities said he planned to start a “terrorist military training facility.”

Khan, 28, was identified as the suspect in Friday’s central London attack that left two people dead and three others injured, Metropolitan Police Assistant Commissioner Neil Basu said.

He was released from jail in December 2018 on an ankle monitor after he plead guilty to terrorism charges in 2012.

Here’s what we know about the suspect:

He was convicted of terror offenses

Police say Usman Khan, 28, is the suspect in Friday's attack in London.

In 2010, Khan and eight others were arrested in London as part of a major counterterrorism operation. Some of the men were accused of terror charges over an “al Qaeda-inspired plot” to bomb the London Stock Exchange, UK police said at the time.

Khan, originally of Pakistan, admitted to other terror offenses involving fundraising and recruiting for a terrorist military training facility under the guise of a madrassa, or educational institution, on land in Kashmir that was owned by his family, according to court documents from the case.

Authorities said Khan’s family land already had a mosque on it and those involved in the plot were looking to infuse the group with cash to “establish and operate a terrorist military training facility,” according to a sentencing document.

Khan and another suspect in the case were accused of planning to train people at the facility with the goal of making them “more serious and effective terrorists,” the documents said.

They were accused of attending operational meetings, fundraising and preparing to travel abroad to “engage in training for acts of terrorism,” according to the sentencing remarks.

Khan pleaded guilty in 2012 to the charges and he was sentenced to 16 years in prison for his role.
