The Arizona Peace Officer Standards and Training Board on Wednesday revoked the badge of a former Scottsdale police officer who bragged about having taught a suspect a lesson by "face planting" him to the ground after forcing his way into the suspect's home.

Nicholas A. Young lost his Arizona peace-officer certification, which means he can no longer work as an officer in Arizona.

According to Scottsdale police internal affairs documents obtained by The Arizona Republic, allegations of unlawful/improper entry, poor judgment, failure to report and integrity violation were made against Officer Young.

According to the documents, in August 2008, Young responded to a shoplifting call. He went to the home of the suspect and was invited in. A short time later, the suspect asked Young to leave. Young left, but continued to question the suspect outside the front door.

The suspect demanded Young leave and began to close his front door. Young forced the door open with either his arm or shoulder, re-entered the home and chased down the subject and forced him to the floor, the documents said.

Young told internal-affairs investigators in November that he was trying to prevent the suspect from using a weapon against him. But the report states that Young used poor judgment by not requesting a back-up officer, which is department protocol. Young also failed to document his actions and tell his supervisor how he entered the home. Young also sent typed messages to a department call taker where he bragged about having taught the suspect a lesson by "face planting" him to the ground.

When Young was interviewed by investigators in November, he said that he'd told his supervisor about how he'd entered the home. His supervisor testified that she wasn't told.

Interviewed in January, when he was presented with the contradiction, Young admitted that he had lied in his previous interview by saying that he'd informed his supervisor of how he entered the home and misled his supervisor.

Young resigned from the Scottsdale Police Department in February.
