OAKLAND --

Oakland police are searching for a man who sexually assaulted a woman and escaped after she took a video of him with her cell phone, authorities said Wednesday.

The 28-year-old woman was alone in her home on the 900 block of Apgar Street in West Oakland when she was confronted by a man who had forced his way inside, said Officer Holly Joshi, an Oakland police spokeswoman.

The woman used her cell phone to record the man as he took electronic items from her and briefly left her home, Joshi said. The man then returned and sexually assaulted her, police said.

The woman was treated at a local hospital.

He is described as a black man in his early 40s, about 5 feet 9 inches tall, 160 pounds, with a bald head and a medium complexion. He wore a blue and white T-shirt and jeans.

Anyone with information is asked to call Oakland police at (510) 637-0298.
