A man putting up graffiti with his brother in the South Bay’s Nestor neighborhood was stabbed three times in the back and sustained life-threatening wounds when his brother’s ex-gang associates attacked the men, police said Tuesday.

The fight broke out about 10:55 p.m. Monday while the victim and his brother were tagging a wall at Nestor Park in the 1300 block of Oro Vista Road, San Diego Police officer John Buttle said.

“The suspects, gang members, saw the tagging and went over to deal with the taggers,” Buttle said. “The gang members recognized the victim’s brother as a jumped-out member” — meaning he was beaten by gang members before he was  allowed to leave the gang.

The suspects began fighting the victim and his brother, who ran to their car “where one of the gang members stabbed the victim three times in the back,” Buttle said. The ex-gang member drove his brother to a hospital, where doctors considered his injuries life-threatening.

“Once the victim was stable he was transferred to a trauma hospital,” Buttle said.

Gang detectives were called out to investigate the attack, which they considered an attempted homicide.
