Akron police detectives are investigating two apparently unrelated robberies that targeted U.S. Postal Service workers a few hours apart Monday.

Officers responded to the first incident around noon Monday at Austin Avenue and Clement Street in East Akron.

A 44-year-old mail carrier told police that two men in their early 20s pulled up to his postal vehicle at the intersection while he was loading his mail bag.

The mail carrier said one pointed a gun and demanded the mail bag and other property. Police said the mail carrier handed over what he had, and the robbers fled.

Police said a second postal carrier was robbed around 2:30 p.m. Monday on his delivery route in the 700 block of Sumner Street in University Park.

The 35-year-old carrier told police he was robbed at knifepoint, saying a man 20 to 30 years old wearing an Ohio State jacket and mask approached him, pulled a knife and demanded a key.

The robber fled northwest with the postal property, police said.

Police said it does not appear the robberies are related, but investigators are looking at any possible correlation between the two incidents.
