OAKLAND -- Two boys, ages 14 and 15, were arrested Sunday on suspicion of carjacking an SUV at gunpoint from a woman in West Oakland, police said Monday.

Police said the 14-year-old was driving the vehicle when police stopped it and later told investigators he was involved in the carjacking "because he liked driving." The boys' names were not released because of their age.

A third teen, believed to be 15, is being sought, and police believe the suspects are responsible for other carjackings in the area.

Police said the 51-year-old Oakland woman was taking something out of her Lexus SUV about 3:40 p.m. Sunday near the intersection of 16th and Myrtle streets when she was approached by the three suspects. One pointed what later turned out to be a replica pistol at her, and the three drove off in the SUV. She was not hurt.

Police spotted the SUV a few minutes later. They pursued it before it stopped near Eighth and Henry streets, where the three suspects tried to flee on foot. The 14- and 15-year-old were captured, but the third suspect escaped.

Police found the replica pistol inside the SUV. The two suspects were arrested on suspicion of carjacking and taken to Juvenile Hall in San Leandro.

Earlier Sunday, two 15-year-old boys were arrested for robbing a 56-year-old woman of her wallet and cash at gunpoint downtown.

The woman was confronted by the suspects about 10 a.m. Sunday on 14th Street, near Harrison Street. One of the boys was armed with what later turned out to be a BB gun, and after robbing the woman, the boys fled on foot, police said. She was not hurt.

Police spotted the pair a short time later in the 300 block of 15th Street and arrested them.

Police recovered some of the woman's cash and a debit card from the suspects, one of whom had a BB gun in his waistband.

The woman identified both boys as the robbery suspects, police said. They were arrested on suspicion of armed robbery, and police believe they are responsible for other robberies in downtown.
