COATESVILLE — The police chief in this southeastern Pennsylvania city plagued by arson says everyone under the age of 18 must be off the streets by 8 p.m.

Coatesville's curfew had been 10 p.m. until the new time announced Friday.

However, a city spokeswoman says through Saturday night, juveniles out between 8 p.m. and 10 p.m. won't get citations as long as they comply with police orders to get off the streets.

Also, the city says police soon will issue citations to people who have combustible items on their porches.

City officials declared a state of emergency last month after a blaze struck 15 row houses, displacing dozens of people.

The most recent arson was Tuesday night.

Coatesville is about 35 miles west of Philadelphia.
