The U.S. Postal Inspection Service has released a sketch of one of the two men they say attacked and robbed a mail carrier last week.

The USPIS is also offering a $10,000 reward for information leading to the arrest and conviction of the robbers.

Police say Aaron Cobb, a 20-year veteran postal employee, was struck in the head and robbed of his master key at the Holly Tree Patio Villas on April 24.

Police say the men got away in an older model van.
