A Black Friday shopper was shot and critically wounded early Friday in a robbery attempt outside a San Leandro Walmart store.

The shooting occurred about 1:45 a.m. as the victim and his family were walking through the parking lot to their car, San Leandro police reported. When a group of men confronted them and demanded their purchases, a fight broke out.

Family members grabbed one of the would-be robbers, a man in his mid-20s, and held him until the police who were already patrolling the parking lot arrived to take him into custody. At least three other suspects are being sought.

Tony Phillips, 20, was arrested on suspicion of attempted homicide and attempted robbery, police said. The shooting victim, whose name was not released, was taken to the hospital in critical but stable condition, police reported.

The Walmart store at 15555 Hesperian Blvd. had opened at 10 p.m. on Thanksgiving for an early start to Black Friday shopping. According to witnesses, the store was briefly closed and the parking lot sealed off as officers sought the attackers.
