A $1,000 reward was offered for the public's help solving a robbery in the Gaslamp area of downtown San Diego, according to San Diego County Crime Stoppers.
San Diego Police say the victim was speaking with a group of men he didn't know inside a Subway restaurant on the 900 block of Fifth Avenue on Mar. 31 at about 2:25 a.m.
Shortly after he walked out of the Subway restaurant, a swift punch on his head knocked him out cold, according to Crime Stoppers.
The robbers took off with the victim's cell phone, watch, shoes and cash, leaving him with several abrasions on his face and head.
Paramedics took the victim to a nearby hospital where he was treated for brain bleeding, according to Crime Stoppers.
A witness saw two men punch and kick the victim while he was on the ground. Both of the suspects were last seen running south on Fifth Avenue.
There are four suspects in this case, based on surveillance video in the restaurant. Anyone with information can call the SDPD's Central Division at (619)744-9500 or Crime Stoppers at (888)580-8477.
If someone has information that helps lead to an arrest, they could receive a reward of up to $1,000.
