Philadelphia Police are asking parents to help enforce the city’s curfew.

“We’re going to be stepping it up with curfew enforcement throughout the city of Philadelphia,” said Philadelphia Police Lt. Mike Goodson.

Summer is starting, school is ending.

Facts of city life in June — and the only people that know better than the teens — are the people charged with their protection.

“We want to make sure that our juvenile population stays safe,” said Lt. Goodson.

Summer curfew enforcement now in effect.

Minors 16-and-older – 11 p.m.

14-15 – 10 p.m.

13-and-under – 9 p.m.

“We’ve been very, very successful,” said Lt. Goodson.

Philadelphia Police Lieutenant Mike Goodson says officers issue curfew violations every year by the thousands and it’s effective.

But he also says it’s not about carrying a big stick, it’s a tool to curb bad behavior.
