"We're working to establish the motive behind this tragic incident and following a number of leads. If you believe you can help us, then please make contact," Det Ch Insp Tunstall said.

There will be an increased police presence in the area, and anyone with concerns or information can talk to those officers, the force said.

Dr Jason Jones, the principal of Richmond upon Thames College, said extra support and counselling is available for students and staff, and security has been stepped up.

"This loss is sure to raise many emotions, concerns, and questions for our students, parents, staff and local community," he said.

"Safety remains our number one priority and we will continue to do all we can to keep our students safe at college.

"To that end, we have enhanced security and surveillance at our entrances following yesterday's incident and are continuing to work in full co-operation with the Metropolitan Police, which is handling the matter."
