Three teenagers and a 20-year-old man are in custody in connection with a series of muggings in Central Park this week.

The teens, ages 14, 15, 17, and the 20-year-old allegedly punched a 19-year-old man in the face at around 7:30 p.m. yesterday inside the park near the Loeb Boathouse, taking off with his cell phone. The victim contacted police, who drove him around until he spotted the suspects on East 76th Street near Madison Avenue. "The police had them up against the wall. They put them in cuffs," a witness to the arrest told the Daily News.

Police believe the suspects are responsible for at least two other muggings in the park this week, one of which occurred by the Central Park Reservoir at about 11:35 p.m.—four teenaged men allegedly robbed two women at gunpoint. Just a few minutes earlier, suspects fitting a similar description allegedly mugged a Queens man near West 96th Street and West Drive, also at gunpoint.

A robbery early Thursday morning, in which two armed men allegedly robbed a man at around 3 a.m. at West 70th Street and Central Park West, is not believed to be connected to the teens in custody.
