Chula Vista police are looking for a serial groper after they received complaints from eight separate women, two more cases were reported in the past two days.
Police say all of the attacker runs up to unsuspecting women and begins molesting them.
"The suspect runs up on the victim and begins grabbing the victims breasts, crotch and buttocks," said Lt. Roxana Kennedy of the Chula Vista Police Department.
In one of the cases, the victim was bitten on the buttocks.
"The suspect in this instance was crowded down in an area and approached her from behind, grabbed her around the waist and pulled her into him. And as she was struggling to get away, he just reached down and bit her, over her clothing on the buttocks" said Lt. Kennedy.
The latest incident happened Thursday at about 2:50 p.m. on Fourth Avenue near I street.
“The 16-year-old victim was walking home from school, northbound on the 600 block of Fourth Avenue, when a male suspect ran up behind her, grabbed her buttocks, turned around and fled on foot,” said Chula Vista Police Dept. spokesperson Bernard Gonzales.
The other case happened Wednesday at 2:45 p.m. in the 100 block of Palomar Street.
“A 15-year-old teenager stated that she was walking home from school when a male suspect ran up to her, grabbed her between the legs, then ran away,” said Gonzales.
Chula Vista police have struggled to find a suspect because they say the attacks are over in a matter of seconds, and the victims have not gotten a good description.
"The suspect in many of the cases has been in a sweatshirt, hooded sweatshirt type of outfit. Even in one case, they took a t-shirt and put it over their head," said Lt. Kennedy.
Chula Vista police are not ruling out the possibility there could be more than one person involved.
"Whether they think it's just a prank and funny, we certainly don't. But beyond that, I don't know that this is going to escalate and I want to make sure the community is aware so women out there on the streets can take precaution," she said.
Police say all of the victims have been Hispanic women. The suspect in nine of the cases has been described as 'light skinned.' In the other case, the suspect may have been African American say police.
There have been ten cases since September.
