Police say that two teenagers have been arrested in connection to an attack of a mailman.
Joseph Raul Navarro-Thompson, 18, and a 17-year-old were arrested on Sunday.
Authorities are still on the lookout for at least two more suspects.
A group of teenage boys is said to have attacked a Yuba City mailman on Thursday. They were targeting a cash box and a necklace the man was carrying.
The U.S. Postal Service announced that they are offering a $50,000 reward for information that leads to the arrest of the suspects.
Navarro-Thompson now faces robbery, assault and participating in a criminal street gang charges.
Anyone with information about the attack is asked to call Postal Inspectors at (877) 876-2455, or the Yuba City Police Department at (530) 822-4660.
