Mesa police said officers were looking for Michael Devin Dietz Ruiz, 29, on multiple felony warrants and after he took off from police around 6 p.m. Monday, confirmed he was in a house on La Donna Drive, near McClintock Drive and Guadalupe Road.
Detectives said Judd Harper, 40, wanted on a probation violation, was also inside the home.
SWAT arrived, and several people came out of the house and told officers that Harper and Dietz Ruiz weren’t coming out.
Police told the two suspects to come out of the house over the loudspeaker, but they refused.
SWAT members then fired four rounds of tear gas into the house. Harper and Dietz Ruiz then came out and were taken into custody without incident.
Dara Man, 45, and Sabra Harrison, 37, were also arrested on felony warrants, police said.
Mesa police said the gas rounds were left at the house, and the police investigation at the house ended around 2 a.m.

Around 4:14 a.m., Tempe firefighters were called to the house because of a small fire and found something burning in the attic. It was removed and extinguished.
The Tempe Fire Medical Rescue Department said crews used thermal imaging and did not find any other fire or signs of heat.
A fire investigator stayed behind and, while looking over the scene, spotted light smoke coming from the attic just before 6 a.m.
“Within minutes, the fire spread rapidly through the attic space,” the department said.
Firefighters arrived and put out the fire.
No one was hurt.
Multiple agencies are involved in the investigation, and no cause of the fire has been determined.
