Concord Police are chasing a man on Queens Road, which is off Willow Pass near Farm Bureau.
The chase began when the suspect took off on foot when he saw officers, and he ended up throwing something (probably drugs) as the chase continued along Queens Road.
The suspect is a white male adult.
UPDATE, 1:08pm: The man ran through somebody’s house, then climbed on the roof. He was taken into custody without incident a few seconds later.
No injuries were reported.
