Robert Galan, 23, Tyrone Pogues, 22, and Jerome Pogues, 22, were booked into jail on suspicion of armed robbery and conspiracy.
Colton police came to a recycling business in the 800 block of North Rancho Avenue about 11:30 a.m. Sunday on a report of a robbery.
The robbers ran from the location and two got into a vehicle. Another law enforcement agency spotted the car at the corner of Third Street and Valley Boulevard.
Tyrone and Jerome Pogues, who were in the vehicle, were arrested.
Police later found the gun used in the robbery at a home near the corner of E and Third streets. While trying to capture Galan, the man jumped out of a second story window and escaped. Officers arrested Galan on Monday after they spotted him walking near the corner of Second and C streets.
