PASCO, Wash.-- Pasco Police have arrested a man in connection with Wednesday's armed robbery of a convenience store.

Investigators posted surveillance photos on social media, showing the suspect who allegedly walked into the Sky Market at Sylvester and 20th at about 8:45 Wednesday night.

The man, who was wearing a mask, is accused of threatening a clerk with a knife and demanding cash.

Investigators say it was a tip from a facebook follower that led them to the Amtrak station about a block away from the police department. That's where they found Eric Quintero, 28, Burbank, and took him into custody.

Officers also recovered a knife.

Quintero is being held in the Franklin County Jail for suspicion of first degree robbery.
