PEMBROKE PARK, Fla. -

The U.S. Postal Inspection Service is offering a $10,000 reward for information leading to the arrest and conviction of two men who attacked and robbed a mail carrier Thursday.

Postal employees were distributing reward fliers Friday to residents at the Holly Tree Patio Villas in Pembroke Park.

That's where Aaron Cobb, a 20-year veteran postal employee, was struck in the head and robbed of his master key.

Investigators are searching for two men who got away in an older model van.
