Two men have been charged with assault on a peace officer and other crimes in connection with an attack on an undercover Oakland police officer in East Oakland on Jan. 21.

Damien McDaniel, 23, and Glenn Wilson are scheduled to be arraigned Tuesday on the assault on a peace officer charge as well as assault with a semiautomatic firearm, second-degree robbery and possession of a firearm by a felon.

McDaniel and Wilson both have prior convictions for auto theft and possession of illegal weapons.

The charges stem from an attack on Officer Eric Karsseboom while he was participating in a stakeout in the 1700 block of Seminary Avenue the evening of Jan. 21.

According to a probable cause statement written by Officer Leo Sanchez, Karsseboom was sitting in an unmarked police car when he was accosted by several suspects, including McDaniel and Wilson.

Sanchez said McDaniel removed Karsseboom's off-duty weapon from inside the car, and Wilson and an unidentified third suspect pointed guns at him.

McDaniel then tried to remove Karsseboom's police-issued weapon from the officer's waistband, and when Karsseboom tried to stop him, Wilson and the third suspect pistol-whipped the officer, causing several cuts to his head, according to Sanchez.

McDaniel then shot Karsseboom in his left forearm and took the officer's service weapon, Sanchez said in the statement.

Karsseboom identified himself as a police officer but the suspects told him they didn't believe him, and at one point said "they don't care if he is in fact a police officer," according to Sanchez.

All three suspects initially escaped, but McDaniel and Wilson were later arrested.
