Pleasant Hill police have released a sketch of a man suspected of stealing cell phones from people in the Contra Costa Boulevard area.
The suspect has been described as an African-American man, 25 to 30 years old, with closely shaven hair and a muscular build.
He's described as wearing a heavy jacket, scarf and beanie cap. He also rides a mountain bike with no kickstand.
Authorities released details of the crimes on Friday.
They said in some cases the man approaches victims from behind and snatches the mobile phones while they are distracted. In other cases, he asks the victim if he can use their phone and then takes off with it.
The thefts have taken place in the Contra Costa Boulevard area between Taylor Boulevard and Second Avenue South.
