Nearly seven weeks in and no immediate end in sight.

That just about sums up where a special team of 20 London police investigators stand with the search for suspects in the March 17 riot on Fleming Drive.

Const. Dennis Rivest said the investigation will continue “indefinitely.”

Police released the latest update in the case on Thursday, laying unlawful assembly and mischief charges against seven people. Four members of the group are charged for destroying a news truck that was tipped and set on fire.

Forty-nine people — 19 who were Fanshawe College students when the incident happened — are now facing criminal charges, Rivest said.

Images of 25 people police have not been able to identify were on the police department’s website Thursday afternoon. That’s down by two from the previous day.

The investigation, Rivest said, has been “incredibly complicated” as officers pore through mounds of video footage shot during the incident. The work’s been made even harder by the fact that many potential witnesses left London at the end of Fanshawe College’s winter term.

Despite that, police consider the investigation a success.

“We’re charging (about) six to seven people a week right now,” Rivest said. “It’s getting the attention it deserves and the resources it needs to bring it to a conclusion.”
