RICHMOND -- Two North Richmond gang members were arrested Wednesday in connection with a shooting, and police are giving credit to an anti-violence initiative for putting detectives in position to catch them.

Antwon Johnson, 19, and Marjuan Crenshaw, 21, were arrested after detectives witnessed a shooting in the area of Kelsey Street and Alamo Avenue in North Richmond just before 4 p.m., Richmond police Det. Nicole Abetkov said. Nobody was injured in the shooting, she said.

The detectives were working in partnership with Ceasefire, a violence-prevention program launched in Richmond in March that utilizes community members, clergy, police and the Contra Costa District District Attorney to single out individuals deemed likely to commit violence, Abetkov said.

Detectives had just left a residence of a singled-out offender on Kelsey Street when they saw the shooting, Abetkov said.

The detectives saw "Johnson flash a gun and heard the shots," Abetkov said. "They recognized Johnson as a gang member from the clothing. It was very distinctive."

Detectives chased Johnson through backyards on Duboce Avenue before catching up to him, Abetkov said. A subsequent search for weapons by police dogs turned up a stolen 9 mm handgun with an extended magazine that also was stolen, Abetkov said

Johnson was booked on suspicion of assault with a deadly weapon and being in possession of a stolen firearm with an extended magazine, both felonies, Abetkov said.

Crenshaw was arrested a short distance away, found by detectives who saw him mingling with a group of people on the street, Abetkov said. He was booked on suspicion of participating in a criminal street gang; obstruction of a police officer and violating parole.

Johnson and Crenshaw both are known North Richmond gang members, Abetkov said. Both were taken to County Jail in Martinez. Johnson was being held in lieu of $130,000 bail and Crenshaw had no bail listed because of the parole violation.
