FREMONT -- Police are investigating two incidents that took place 20 minutes and about 2½ miles apart in which two women were accosted while walking home Tuesday night.

Neither victim was physically injured, police said.

The first attack was reported about 7:30 p.m. on the 4000 block of Lana Terrace, just south of Fremont Boulevard in the Cabrillo neighborhood, said Detective Bill Veteran.

A 19-year-old Fremont woman told officers she was walking home when a man approached her, pointed a handgun at her and stole her cellphone before running away, Veteran said.

Then, at 7:50 p.m., a 32-year-old Fremont woman was grabbed from behind while walking from her car to her apartment on the 3500 block of Pennsylvania Avenue, Veteran said.

The woman told officers the suspect grabbed her shoulders, but she screamed, broke free and ran off before calling police.

Her attacker was not armed, Veteran said.

The suspect in the first incident is described as a black man in his early 20s, about 5 foot 10 inches tall, with an average build. He wore dark pants and a black hooded sweatshirt with a white T-shirt underneath it.

The person in the second attack is described as a boy in his teens of unknown race, standing at 5 foot 10 inches tall with a stocky build. He wore a black and gray hoodie with bluejeans.

Anyone with information about the armed robbery or the battery can call police at 510-790-6800 or the anonymous tip line at 510-494-4856.
