Koramangala police have registered a case and launched an investigation. They are making efforts to trace the suspect, Joseph, a delivery partner with Blinkit.

Paul J Vithayathi, 27, a native of Kerala, told the police that he placed an order on Blinkit around 2 am on March 7. The delivery agent called him and said he was on the way to deliver the items.

However, instead of going to his second-floor flat, the delivery agent allegedly went to the fourth floor. When the customer requested him to come to the correct floor, the delivery agent allegedly picked a quarrel after coming near the flat, punched him in the face and scattered the ordered items before fleeing.

Vithayathi sustained severe bleeding injuries near the nose and lips. Doctors told him he had fractured the nose bone in the assault.
