Thesis spat 'spurs' knife attack on lecturer

Two people were arrested yesterday in connection with a knife attack on a Chulalongkorn University lecturer over a dispute allegedly sparked by a bad grade he gave four years ago.

Prapansak Promngam, 25, and Sasithon Tiyakhot, also 25, were charged in connection with Monday's knife attack on Jirawat Cheevarungroj, 49, a deputy dean of the Faculty of Engineering's Mining and Petroleum Engineering Department, at the Pathumwan campus on Monday.

The lecturer was ambushed by an attacker and slashed on the arm and back.

He was taken to Chulalongkorn Hospital where he received 20 stitches.

Mr Prapansak was apprehended yesterday in front of Surasak Montri school in Din Daeng. He was charged with assaulting Mr Jirawat.

Officers seized a box cutter and a motorcycle allegedly used in the attack.

Police said surveillance camera footage and witness statements led them to Mr Prapansak. He was wearing a wig during the attack, they said.

The other suspect, Ms Sasithon, was arrested at her home in Thawi Watthana district yesterday. She was charged with planning the attack based on testimony given by Mr Prapansak.

According to Mr Prapansak's police statement, Ms Sasithon, his former classmate, approached him to help her get revenge on the deputy dean.

Ms Sasithon was furious with Mr Jirawat for rejecting her girlfriend's thesis, which stalled her graduation, police said. The thesis row occurred about four years ago.

Ms Sasithon denied the charge and told officers she would give her statement in court.
