OKLAHOMA CITY - Oklahoma City police arrested one suspect and are looking for one more who robbed and stabbed a Good Samaritan at an apartment complex.

According to police, on December 21, 2014, officers responded to the report of a robbery at an apartment complex, located at 11225 N. Penn. in Oklahoma City.

Police said the victim was flagged down by two men in the parking lot. The men told the victim that their car wouldn't start and they needed a jump. The victim tried to help the two men start their car, but they were unsuccessful.

According to police, the victim agreed to drive the two to an apartment on the other side of the complex. Once they were in the car with him, the two struck the victim in the head with a dumbbell and stabbed him with a knife.

The two suspects then took the victim's wallet and cell phone, and even tried to take his car. However, police said the suspects' attempt to steal the car was unsuccessful because they didn't know how to start a push-button ignition.

The incident was captured by surveillance cameras in the area. Police released the video on Monday, January 12.

According to police, officers were able to identify one of the suspects as 23-year-old Anthony Markus McNack, and take him into custody. The unidentified suspect is the male wearing the beanie cap as seen in the surveillance video. 

Anyone with information regarding his identity should call Crime Stoppers at (405)-235-7300. Callers can remain anonymous and may be eligible for a cash reward.

McNack is being held at the Oklahoma County Jail on a complaint of robbery with a dangerous weapon. His bond has been set at $40,000.
