UPDATE: Serial bank robber suspect arrested

A mother of a suspected bank robber sent him an impassioned plea during an interview Thursday to turn himself in.

Nickarlos Banks, 34, is wanted for multiple bank and convenience store robberies.

Little Rock police say that because Banks showed a weapon in his most recent bank robbery Thursday morning, he is even more dangerous and the crimes are escalating.

Detectives want to arrest him. His mother Jaclyn Turner wants him to give himself up.

"Your mama still loves you so please turn yourself in," Turner says. "Stop doing what you're doing and give yourself up. That's the best way to get you some help," she begs her son.

Police say surveillance pictures show him in a wig, holding up Delta Bank & Trust at 2924 Kavanaugh Thursday morning.

Little Rock Police Lieutenant Terry Hastings told FOX16 News that Banks is homeless and may have boarded at CATA bus after the robbery.

"He is strictly robbing these businesses and banks for the drugs. He's trying to get money to buy crack cocaine," Hastings says."

Detectives say Banks took off running west on Kavanaugh and into a neighborhood where he dropped $250 on the ground near Clarkson & H.

Carolyn Wallace lives nearby and was walking her dog "Rio" when she spotted the cash and called 311.

"First I saw one 50-dollar bill and then I kind of looked around and there were four others," she said.

Turner hopes police arrest her son or turns himself in before he kills somebody or gets himself killed.

"People still love you, your whole family does," Turner said through tears. "Don't make us suffer."

Banks is also wanted for robbing Allied Bank at 4900 Kavanaugh on October 27th.

Police say the pervasive motivation for the robberies is crack cocaine. The money taken from the banks just a means to an addictive and dangerous end.
