Chandler police have arrested a 19-year-old man in the Chandler Fashion Center shooting as he was shopping at the mall a day after officials said he fired 30 rounds from an assault rifle in the center's parking lot.

The arrest was made shortly after 11 a.m. Tuesday, Aug. 2, at the mall, 3111 W. Chandler Blvd.

The day before police responded to a  call at 6:58 p.m.  at the mall  to a report of gunfire in the parking lot.

There, police said, they found shell casings from an AR-15 assault rifle and determined that they were fired by a man his late teens to early 20s, with numerous tattoos.

Police also learned that an incident between the man and another individual led to the shooting.

"Before the shooting, the male suspect pointed a rifle at a victim, demanding property. The male suspect fled the location in a vehicle before the arrival of police. Police found no one was injured, and no damage to property," according to a report from Chandler police.

That night, detectives identified the male suspect as Nathaniel Anthony Vensor, 19. Police said they did not find the suspect until the next day when they were called to the mall again with reports from security of Vensor shopping inside the center.

"As officers arrived, video surveillance captured Vensor shopping. Police arrested Vensor at 11:03 a.m. Vensor was unarmed and wearing the same baseball cap he purchased at the mall before the shooting," the report stated. 

Vensor was booked into the Maricopa County Jail on one count of armed robbery, one count of aggravated assault, one count of possession of a weapon by prohibited possessor and 30 counts of unlawful discharge of a firearm.

Also, police said, Vensor possessed a narcotic drug upon his arrest and was booked on one count of possession of narcotic drugs.
