A barricade situation near 33rd Avenue and Thunderbird ended peacefully after a former Maricopa County Sheriff's deputy refused to come out for eight hours.
40-year-old Ramon Armendariz's roommates called 911 around 5 p.m. pm Sunday saying the man had a gun and was threatening to hurt himself.
When officers arrived, the suspect allegedly refused to come out of the home.
Phoenix police Sgt. James Holmes says the situation was more difficult because the man has knowledge of police tactics, but that he also knew how long officers would wait outside.
Officers say the situation eventually ended peacefully around 1:30 a.m. when the man voluntarily left his home.
Armendariz was arrested for alleged possession of dangerous drugs and drug paraphernalia.
Phoenix police first became aware of Armendariz on April 30 when he called 911 saying a burglar was inside his home. When officers arrived, police say he was armed with a pepper ball gun and chasing a phantom burglar.
Armendariz reportedly resigned on May 2 after a search warrant was served to his home.
He has worked with MCSO in various areas of the office since May 2005.
