A Montgomery County man was arrested in Prince George's County after he shot a childhood friend, took off his clothes, climbed onto a firetruck while naked and was shot with a Taser by police, authorities said.

Mohamed S. Bah, 24, was charged with attempted murder, assault and other offenses. Prince George's County police said Bah was high on PCP during the incident.

Late Wednesday afternoon, Bah, the victim and a third person were in a vehicle, when Bah suddenly turned toward the victim and shot him. Bah and the third occupant then bailed out of the vehicle, and it crashed into at least one parked vehicle, police said.

Officers were called to the 11900 block of Beltsville Drive in Calverton for the report of a car accident and found the 24-year-old victim suffering from a gunshot wound to the head. The victim was taken to a hospital and was in critical condition Thursday afternoon but is expected to survive, police said.

Police then received another call about a disorderly naked man in a nearby shopping center. Officers found Bah on top of a Prince George's County firetruck, unclothed, and yelling profanities and threatening to kill people, according to police and a court document.

Officers gave Bah verbal commands to come down, but he continued to make threatening remarks. After several minutes, Bah came down from the firetruck, and an officer used his Taser on him, police said.

Bah was then handcuffed and taken to a hospital. Upon release from the hospital, he was taken to a police station for an interview and then to jail. Bah was being held without bond Thursday afternoon, police said. A handgun has been recovered.

The scene at the firetruck was caught on video. Maj. Mark Person, commander of the Prince George's Police Department's Training and Education Division, said that police plan to show the video in the training academy because the Taser deployment and apprehension happened quickly without any officer injuries.

"This was a textbook Taser usage for us," Person said. "It could not have gone any better."

Person believes officer injures have decreased since police began using Tasers. Before the electric stun guns were available, police would have had to fight a suspect like Bah -- likely resulting in injuries to police and/or the suspect.

Police said they do not know of any reason for the shooting other than perhaps Bah's intoxication. Person said that often when people are high on PCP, they "simply don't know what they're doing."
