Two Hempstead teens who police say stole cellphones from at least five victims in nine days, using a knife in one instance to threaten a 12-year-old boy, were arraigned Saturday.
Curtis Williams, 15, and Teisean Kemp, 14, were arrested Friday and charged as adults with one count of first-degree robbery.
"You are skating on thin ice," warned Judge William O'Brien, who granted a conditional release for both teens. "I can send you to jail right now."
Neither entered a plea in First District Court in Hempstead.
"My son is a follower, and I'm trying to save him," Curtis Williams Sr. said after the proceedings. "I am worried about my son."
Kemp's family declined to comment.
During the crime spree, the teens snatched cellphones from victims' hands or pockets in Hempstead and ran off, Nassau County police said. No injuries were reported.
Williams and Kemp allegedly robbed a 14-year-old boy on Nov. 28, a 15-year-old girl on Tuesday and the 12-year-old at knifepoint on Thursday.
On Friday morning, they attempted to take a cellphone from a 20-year-old man, who fought them off, police said. The pair is accused of robbing a 17-year-old man, who briefly gave chase, later that day on Seabury Street.
The teens are due back in court Tuesday.
Police believe there are additional victims. Anyone who believes they may have been robbed by the suspects is asked to contact Third Squad detectives at 516-573-6352.
