A man was robbed at gunpoint Thursday afternoon during what the victim says was a legal marijuana deal, Officer Steve Goard said.
The man, who is not a Livermore resident, told police that he legally purchases the drugs from a medical marijuana dispensary.
"(The victim) says he has a website to sell marijuana online," Goard said.
The man called police at 2:40 p.m. to report that he was held at gunpoint at the intersection of South Vasco Road and Brisa Street — a location he agreed to make a transaction.
When the victim pulled off on the side of a road he was robbed at gunpoint of his marijuana, phone, wallet and keys, Goard said.
The victim estimates that he had about a pound of marijuana taken from him.
He also told police a silver handgun was used in the robbery.
The four suspects are all described as black males and appear to be from out of town, Goard said. One of the suspects is described as heavy set with dreadlocks. They were last seen traveling northbound in a vehicle on Vasco Road, police said.
Police continue to investigate the robbery, Goard said.
