CALDWELL -- A Boise man accused of participating in a drive-by shooting near Caldwell's Luby Park Monday has been arrested.

Roberto Angel Ballesteros, 30, is facing felony charges of aiding and abetting aggravated assault, shooting into an occupied vehicle, and felony possession of a controlled substance.

The drive-by happened at about 8:50 p.m. at North Illinois Avenue and Marble Front Road. Police say the occupants of a car opened fire at another vehicle. The targeted car was hit multiple times but the victims, aged 18 and 20, were unhurt.

It's unclear whether Ballesteros acted as the driver or shooter during the attack, police say. He was arrested at a Boise hotel Tuesday night by detectives from the Caldwell and Boise police departments.

As he was being taken into custody, officers discovered Ballesteros had methamphetamine in his possession, police say.

Police say they've recovered the car used in the drive-by - a white Dodge Journey - but the other suspect in the drive-by is still on the loose.

That man was described as shorter and stockier than Ballesteros. He wore jeans and a black long-sleeved shirt at the time of the shooting.

Police say they victims and suspects may know each other, and the shooting is not believed to be random. Ballestros and the 20-year-old victim are documented members of rival gangs, but police have not yet confirmed the shooting is a gang-related crime.

Anyone with information about the second suspect's whereabouts is asked to call Crime Stoppers at 343-COPS.

Ballesteros is currently held in the Ada County Jail, and is due to appear in court Thursday afternoon.
