An Egyptian police corporal was arrested late on Monday on charges of shooting his colleague dead after a fight between the pair, the Interior Ministry said in a statement.

Wael al-Shabrawy said he shot his colleague dead on Monday because the latter “used to frequently mock him in his Facebook comments, telling him he was not funny,” according to investigators.

Medical examiners said the victim sustained two shots in the belly.

The Interior Ministry’s statement said the officer argued with his colleague in the restroom of al-Zohour police station before shooting him dead.

Police detectives revealed Shabrawi was sacked from the police service in 2007 for “frequent violations” before being recalled after the 2011 uprising.
