AZUSA — Police arrested two men and two men Saturday on suspicion of trying to carjack a man at a gas station.

Edgar Alba, 25, Anna Rodriguez, 19, and Christine Van Frankfoort, 26, all of Azusa, along with Amado Trejo, 20, of Duarte were booked on suspicion of attempted carjacking, according to Azusa police Sgt. John Madaloni.

The victim was at a gas station in the 300 block of East Foothill Boulevard about 3:30 p.m. when two men and two women approached, the sergeant said. One of them motioned as if he had a weapon in his waistband.

“After they attempted to steal the vehicle, the suspects aborted the crime for unknown reasons and drove off in their Toyota SUV,” Madaloni said. The victim followed from a distance in (his) vehicle and called police.”

Within minutes, officers spotted the suspects’ SUV parked in the 400 block of North Alameda Avenue, police said. Three of them were standing nearby.

As officers detained the three suspects near the SUV, the fourth suspect emerged from a nearby house, but then darted back through the home and into an alley, Madaloni said. He was found and detained about an hour later.

“All four suspects were positively identified by the victim and witnesses, and arrested,” Madaloni said.

County booking records indicated Alba, Rodriguez, Van Frankfoort and Trejo were being held in lieu of $100,000 bail each and were due for arraignment Tuesday in West Covina Superior Court.
