A high electricity bill is believed to have caused tension to run even higher at Seberang Pintasan in Dungun, Terengganu today, resulting in a Tenaga Nasional Berhad (TNB) personnel suffering minor injuries after being roughed up by an unknown individual over the matter.

Terengganu TNB retail department customer services head Mohd Nazri Puteh said this was the first time such an incident had occurred in the state.
