An arrest warrant has been issued for a Starr County man accused of firing a shotgun at a vehicle and then fleeing the scene. 

Agustin Rodriguez, a resident of Starr County, is wanted on an aggravated assault with a deadly weapon charge, according to the sheriff's office. 

At about 8 a.m. Wednesday, deputies responded to Junior St., west of the Rio Grande City limits, in regards to shots fired. 

Deputies met with witnesses who said that a man, later identified as Rodriguez, shot at a vehicle with a shotgun, then fled the scene towards the river. No injuries were reported.
