On Monday, a food deliveryman in Rome stabbed a colleague during a confrontation that erupted over an anti-Semitic rant in front of McDonald’s.

The assailant, who works for the Delivroo service, launched into a tirade about Jews as he waited for an order at the fast food giant’s Piazza dei Re di Roma square location, JTA reported.

The victim, an employee of competitor Just Eat who was also waiting to pick up an order for delivery, objected to the assailant’s anti-Semitic rant.

In response, the Deliveroo deliveryman pulled a knife and stabbed the Just Eat employee, Italian news website Faro di Roma reported.

It was unclear from reports in the Italian media whether the victim was Jewish.

Both men were described as “middle-aged” by Faro di Roma.

Immediately following the attack, the assailant fled on his motorcycle.

Rome law enforcement are reportedly searching for the suspect.
