An 11-hour Sandy Springs SWAT standoff with an infant hostage ended Monday night without incident, police said.

"We're about done here," police spokesman Capt. Keith Zgonc told The Atlanta Journal-Constitution shortly after 9 p.m. "He's in custody, and the baby's fine."

Police identified the suspect as 33-year-old Clinton Bailey . He is charged with two counts of aggravated assault and possession of a firearm during a crime, Zgonc said.

The hostage situation began around 9:45 a.m. at the One Sovereign Place apartment complex. Zgonc said the "individual walked into the leasing office, making some claims that something was wrong with his water, claiming that somebody was messing with his water.”

“He had a gun, waved it around [and] pointed it at a couple of people in the leasing office,” Zgonc said. “He left the leasing office [and] walked back to the apartment.”

Roswell Road in Sandy Springs was shut down after Bailey locked himself and the 7-month-old girl inside an apartment.

The standoff ended when police negotiators talked Bailey out of the house, Zgonc said.

"Negotiators were talking to Mr. Bailey and he came out onto the [back] porch," Zgonc said. "While negotiators distracted him, an entry team went into the apartment and got the baby,  then police took him down."

The child's relationship to the suspect was not clear.

Zgonc said that when speaking with police, the suspect indicated the child lived at the apartment.

The child’s mother, Lindsay Rodgers, who arrived at the apartment complex around 7:30 p.m., was later arrested and charged with obstruction, Zgonc said. Police said the 27-year-old did not cooperate with authorities or provide information about Bailey.

"Rodgers was in the area for several hours, and had actually been in contact with the suspect while detectives were negotiating," Zgonc said.

Zgonc said officers spent a good part of the day trying to reason with the man, who is in his 30s.

“We had received word that he sometimes cares for and watches an infant inside that apartment,” he said.

Zgonc said that while no shots were fired, authorities shut down Roswell in both directions around 11:30 a.m. as a precaution.

Police found three handguns and ammunition inside the apartment, he said.
