TEMPE, Ariz. -- A police standoff in a neighborhood near the Tempe-Phoenix border has ended after the suspect was not located inside the home, according to Tempe police spokesman Lt. Michael Pooley.

Police are still searching for 32-year-old Mark Aceves, who is wanted for a probation violation.

The Tempe SWAT team surrounded a home near 43rd Street and Apollo Road, which is south of Southern Avenue, after a resident reported that someone might be in the attic.

Nevitt Elementary School nearby was placed on lockdown.

Pooley said the SWAT team and probation officers searched that home and Aceves' listed residence.

Detectives from the department's gang unit had tried to contact Aceves around noon, but he fled in a vehicle with two other occupants.

Pooley said the vehicle stopped near 44th Street and Vineyard Road, and Aceves fled on foot. He was then believed to be barricaded inside the home.

According to Tempe Police Sgt. Steve Carbajal, the other occupants of the vehicle were taken into custody.

It is unknown if Aceves has a weapon.

"Based on some previous contacts, we would treat someone like this as armed and dangerous," Carbajal said.

According to the Tempe Elementary School District, the lockdown at Nevitt Elementary School has been lifted, and all students and staff are safe.

Anyone with information is asked to contact the Tempe Police Department.
