A school teacher was killed and a vocational student seriously injured in a shooting near a school in Bangkok’s Khlong Toei district on Saturday morning.

Khlong Toei police say they suspect that the shooting stemmed from a rivalry between students of two vocational colleges.

Quoting motorcycle taxi drivers, police said that a group of about five vocational students were gathered on the pavement in front of a bank, near a girl’s school on Sunthorn Kosa Road, when the pillion passenger from a motorcycle approached the students and opened fire with a handgun. The bullets hit one of the students and a bystander, later identified as a school teacher.

The gunman, thought to be a student at a rival college, walked back to his accomplice on the bike, but was told to go back shoot the already wounded student again. The attackers then fled on the motorcycle, heading towards Rama 4 Road.

The two wounded people were rushed to Chulalongkorn Memorial Hospital, where the teacher was pronounced dead.
