Police on Monday arrested three suspects in the attempted armed robbery of a Metro PCS store in Fairfield last week, police said.The crime occurred at about 3:15 p.m. Friday at a Metro PCS store at 2023 N. Texas St.The robbery was foiled when a Metro PCS employee pulled out a gun and fired at one of two suspects who had entered the store, hitting one.The pair then fled through an open field onto Tabor Avenue,police said.Police received a tip that helped them identify the wounded suspect, a juvenile, who was treated for a gunshot wound to the shoulder at a Bay Area hospital on Friday, Lt. Darrin Moody said.Detectives conducting surveillance on a home in north Fairfield on Monday spotted the injured suspect loitering in a park with another male in the 2900 block of Camrose Avenue. He was arrested and booked into Juvenile Hall, Moody said. Police also searched a home where the juvenile suspect had been, Moody said. Also on Monday, Detective Tony DeTomasi was in Solano County Superior Court on an unrelated matter when he saw a young man he recognized from prior police contacts, Moody said.The man was wearing distinctive clothing and jewelry similar to that worn by one of the suspects in the attempted robbery, which was caught on surveillance video, Moody said.After questioning, the man, 18-year-old Andrew Holiman of Fairfield, was arrested in connection with the attempted robbery, Moody said.Detectives also identified a third suspect, 22-year-old Tyrone Webb, of Fairfield, who they believe drove the getaway car and took the wounded suspect to the hospital, Moody said. Webb also was arrested Monday. Holiman and Webb were booked into Solano County Jail on charges of attempted robbery, burglary, use of a firearm and conspiracy, according to the jail booking log.Moody said cooperation between police and the community and DeTomasi’s observations in the courtroom helped police make the arrests quickly.
