A lone police officer answering the 911 call pulled into the parking lot outside the bank and exchanged gunfire with the bank robbers, Lopez said. During the shootout, Bonner suffered a laceration on his leg.
Yureli Gomez, the manager of Taqueria Arandas, a restaurant nearby, was about to leave for the bank to get some change when her sister came screaming into the restaurant's back door.
"My sister came in and said she saw a robber ran around the bank and then the police officer was behind shooting at him and he went into the bank's back door," Gomez said.
Sharpshooters quickly were dispatched and laid out across the perimeter, hiding behind vehicles, shrubbery and in a Walmart parking lot nearby.
As the suspects attempted to flee through the back door of the bank, gunfire broke out between them and the police's first responder. While two of the suspects retreated back into the bank, another suspect or suspects fled the scene in a dark blue truck, according to ABC News Houston affiliate affili.
One of the two who had retreated inside then fled the bank, but was quickly apprehended in the Walmart lot, KTRK reported. The man has been identified as Raymond Tierra Johnson.
A five-hour hostage standoff between the police and Bonner then ensued. Two hours into negotiations, Bonner released five hostages.
Lewis was one of the hostages allowed to leave. He was caught up in the drama when he went to make a deposit, his girlfriend Donetta Gardner told ABC News.
"When he got out, the sergeant of the police department called me to say I could talk to him for 10 seconds and he told me not to worry and he was OK," Gardner said.
Around 4 p.m., after five hours of negotiating, Bonner released the final two hostages and surrendered, according to KTRK.
Afterwards, three bank employees emerged from a closet where they had been hiding during the ordeal, unbeknownst to Bonner. Police said that they were aware that the three employees were hiding, but to keep them safe did not inform Bonner of their presence.
A total of 10 hostages walked away unharmed, which included five bank employees and five bank customers. Police are continuing to question the hostages as well as the suspects to compile a minute-by-minute account of what happened inside the bank.
"This ended the best way it possibly could," said Lopez.
The police believe one or two suspects got away after the robbery and said that the dark blue truck that fled the scene of the robbery later was recovered.
Both Johnson and Bonner have criminal records that, between the two of them, include aggravated robbery, rape and burglary, according to KTRK.
Officials at Chase bank praised law enforcement for the successful negotiation.
"We are very relieved that the situation at our Pearland, Texas, branch was resolved and thank the FBI and police for their tremendous courage and help," said Mary Jane Rogers, Chase spokeswoman.
"We are working with employees and customers who were at the scene to provide any assistance they or their families need," Rogers added.
