Two Santa Rosa men were arrested Monday on suspicion of marijuana sales after they were tied up and robbed at gunpoint, Santa Rosa police said.

Hector Miguel Serrano, 26, and Antonio Amador Siordia, 23, were confronted by two unknown and armed men in the driveway of a Barham Avenue home near Olive Street in southwest Santa Rosa, Sgt. Steve Fraga said.

The robbers "marched them into the house and tied them up" with their shoelaces, Fraga said.

The robbers stacked about 10 pounds of processed pot by the front door, but at some point they realized Serrano's uncle had dialed 911, Fraga said. One of the men grabbed the phone from 53-year-old Javier Salazar Gomez, hung up and tied him up as well.

But the 10:46 a.m. 911 call already had gone through. When the robbers saw police arrive, they fled out a back window and left in a red Chevrolet Tahoe with dark windows and chrome rims, Fraga said.

Officers untied the men and found the stacked pot, worth about $10,000. Serrano and Siordia provided few descriptions of the robbers, Fraga said.

Detectives searched the home and a home Serrano shares with his girlfriend on McBride Lane north of Coddingtown Mall where they found a stolen rifle and evidence of pot sales, Fraga said.

Serrano was arrested on suspicion of possession of marijuana for sale, possession of stolen property, conspiracy and violating probation.

Siordia was arrested on suspicion of possession of marijuana for sale and conspiracy.

Serrano's girlfriend, Esbeida Campos Valdovinos, 20, was arrested on suspicion of conspiracy to distribute/sell marijuana and possession of stolen property.

Anyone with information is asked to call police at 543-3590.
