He is believed to be a suspect in two sexual assaults and robberies that took place in Oakland on the nights of January 6 and 12. The first occurred when a 28-year-old woman was walking on the 1200 block of Market Street. Police said she was approached by a person who simulated a firearm and demanded her wallet. The suspect then forced her to an isolated area, where he sexually assaulted her.

In the second attack, a 28-year-old woman was walking on the 600 block of 11th Street when she was approached by a person riding a bicycle. Once again, the suspect simulated having a handgun and demanded the woman’s purse. He forced her to an isolated area where he sexually assaulted her.

Oakland police spokeswoman Johnna Watson said that it is unusual for them to release the identity of a minor in an ongoing investigation.

“We’re dealing with a juvenile so the law does not allow us to release his photo to the media and to make the public aware of this particular threat to the community,” said Watson. “But the law does allow us to release his name and a physical description.”

Police said that they believe Glasper is armed and dangerous.

Oakland police are asking for the public’s help in finding the suspect. Anyone with information is asked to contact the Youth and Family Services Division at (510) 238-3641. They are also advising women to be aware of their surroundings.
