FRESNO, Calif. (FOX26) — The Fresno Police Department have arrested three people in two separate incidents involving United States Postal Service (USPS) employees.

The first incident happened Tuesday afternoon, around 2:20 p.m., near North Marks and West Dakota avenues.

Officers responded to reports that a USPS mail carrier had been assaulted while delivering mail to a community mailbox.

Police say the employee was attacked after a suspect demanded money.

Investigators say the victim was repeatedly struck in the head and face and placed in a chokehold, making it difficult to breathe.

No property was taken during the attack.

Detectives later identified two suspects connected to the assault.

Ramey warrants were issued, and both were taken into custody Wednesday.

They are facing charges of attempted robbery and assault with force likely to cause great bodily injury and were booked into the Fresno County Juvenile Justice Campus.

In a separate incident the same day, officers responded to reports of another USPS employee who had a knife pulled out on him in the area of East Cornell and North Maroa avenues.

That USPS employee reported that a man pulled out a knife after the mail carrier used pepper spray to stop an aggressive dog while delivering mail.

Detectives identified the attacker as Brett Timothy Thomas.

While the postal worker initially did not want to press charges, investigators reviewed video of the incident and later obtained a Ramey warrant.

Thomas was arrested and is expected to be booked into the Fresno County Jail on charges of pulling out a weapon and possession of a dagger.

Fresno police say a third, unrelated incident involving a USPS employee was reported Thursday near West Hammond and North Fruit avenues.

That case is being investigated by the U.S. Postal Inspector’s Office.

The Fresno Police Department says it remains committed to protecting postal workers and ensuring the safety of the community.
