Police are searching for two suspects accused of robbing a local mail carrier last week in East Liberty.
Investigators say the mail carrier was filling his van with gas along North Negley Avenue just after noon on Friday.
Two men in their early 20's approached him, made small talk and then demanded he hand over his arrow key.
It's a skeleton key that gives access to most mail boxes.
The victim gave the key to the suspects and was not hurt.
Police say the suspects were wearing black sweatshirts with blue jeans and driving a black sedan with heavy tint in the back window.
The US Postal Inspection Service is investigating.
