The NYPD is investigating what they are calling two separate patterns of sex assaults in the borough.
The latest incident happened Sunday night, when a woman was assaulted after she got off the bus.
Police say the 23-year-old woman got off the bus at Edgewood and South Conduit Avenue in Laurelton around 7:30 p.m. A man, thought to be in his early 20s, approached her and punched her twice in the head. She struggled with him, and he ran off.
Two Good Samaritnas heard her screams and came to the woman's aid.
"We were on balcony watching game and we heard help, help. She came around the corner," said June Balloon, a resident.
"Her mouth bloody, her eyes bloody, her knee. She had no shoes on. Hysterical. 'Please help me. The guy is trying to rape me. Guy is trying to rape me,'" described Patrick Paret, a resident.
Police say that man may also be connected to an attack earlier this month. They've produced a sketch of the suspect wanted in that assault. In that instance, the man approached another 23-year-old woman at night, sexually assaulted her and escaped.
Lastly, police are investigating a separate pattern of attacks, a string of six of them.
Those assaults began in early September and continued into October. In all of the incidents, the suspect rides up to a woman on a black mountain bike, gropes her, then peddles away.
