The NYPD is beefing up security in city parks after two separate sexual assaults Monday night.
Cops say a 13-year-old girl was raped in Claremont Park in the Bronx around 10 p.m.
Investigators say a man assaulted the teen while a woman served as a lookout.
Police are also looking into another incident in Central Park.
They say a woman was walking near East 107th street around 10:30 when she was thrown to the ground by a man who tried to rape her.
He ran out of the park after she pushed him off.
Police believe the man in his 30s, and was last seen wearing a dark jacket and orange t-shirt.
Cops say the two incidents are unrelated.
Investigators are also searching for a group of men who have been robbing cell phones from both joggers and bikers in Central Park.
They're posting extra police presence in parks this week.
"There will be more officers both inside the park and around the perimeter," said NYPD Chief Carlos Gomez. "The precincts that border the park are also giving it extra attention and extra patrols. You’ll see more officers in uniform. There will be plainclothes officers patrolling the parking, as well as officers on scooters"
Police say the robberies have contributed to an uptick in park crimes this month, but overall, crime has been down 17 percent in Central Park this year.
