Long Beach police on Tuesday afternoon set up a perimeter in Alamitos Beach while searching for a man they believed was wanted on a warrant, officials said.

Police were initially called to Broadway and Esperanza Avenue for a dispute at about 12:40 p.m., officer Ivan Garcia said. While they were on their way, dispatch ran the name of one of the people in the dispute and told officers that he might have been wanted for an outstanding probation violation, he said.

When officers got there, a man ran from the scene and police believe he was the suspect wanted on the warrant, but they don’t know for sure yet, according to Garcia. Officers set up a perimeter in the areas around Falcon Avenue and Second Street and Esperanza Avenue and Broadway to search for the suspect.

Residents on NextDoor reported that police on loudspeakers instructed them to stay indoors as officers searched the area with guns drawn. They also reported that police said the man was armed, but Garcia said there was no reason to believe he had any guns on him. The warrant was for a weapons violation, which could mean a broad spectrum of things, Garcia said.

After about two hours, police determined the suspect had escaped. Police are still investigating.
