CENTRAL FALLS — The Central Falls Police Department will give teenagers a break for Halloween: its curfew will be 10 p.m. instead of 9 p.m. on Saturday for trick-or-treaters, out for Halloween, but the department is not hoping to see any tricksters.

The police will be taking precautions with more patrols and unmarked cars, according to Capt. James Mendonca.

The city’s curfew, which normally runs from 9 p.m. to 5 a.m. for teenagers under younger than 18, was imposed by the city in May 2008 after two teenagers were shot to death in the city. Twenty-year-old Anthony Strobert was sentenced to serve 27 years at the Adult Correctional Institutions last December after he pleaded guilty to murdering Helder Tomar, 19, of Pawtucket, in April 2008 in Jenks Park in Central Falls. There have been no arrests in the murder of 16-year-old Edelmiro Roman, who was shot to death on Dexter Street while on his way home, but the investigation continues, Mendonca said.

Chief Joseph Moran, who lives in the city, said that the curfew has served to keep teenagers off the streets. He said he sees it in his travels through the city and his officers report that teens are off the streets after 9.

The department spent several months educating teens and their parents about the curfew, giving those on the streets after hours warnings at first. From January 2009 to the present, Moran said, 37 teens were stopped for breaking the curfew. The number includes five teens who broke the curfew a second time. Their parents were fined $100. One teen broke the curfew a third time and his parents were issued a $200 fine. The first time a teenager is caught breaking the curfew, he and his parents are given a warning. After that the parents are fined.

“Before, the kids were wherever they wanted to be. They’re not silly. They know that they have to be off the streets,” Moran said. “This puts the responsibility back where it belongs, with the parents.”
