London police are staying mum about a joint investigation in a north end neighbourhood.

City police, along with OPP have been investigating on Bridal Path, near Kipps Lane. Witnesses tell CTV London that officers have been there for three days.

Investigators from both sides could be seen Wednesday night scouring the area near a bike path, which was closed to the public.

It may be related to an unsolved crime.

A small excavator was digging in the area and some small trees had been cut down to clear some space

Officials would only say they’re conducting an evidence search after receiving a call from a member of the public.
