Four persons were arrested by the Royapuram police for the murder of the leader and general secretary of the Anna Employees Union for container lorries in north Chennai.
The police said the 26-year-old main accused, Vignesh, had gone to the container lorry yard in Manjambakkam in north Chennai about six months ago to ask A. Vincent, who owns a few lorries, for a job.
They got into an argument over a petty issue and Vincent threatened and humiliated Vignesh, the police said.
“Vignesh wanted to take revenge and hatched a plan with his friends. On Tuesday, when Vincent went to Tondiarpet, he was hacked to death,” said a police officer. Vignesh and the other accused — Sukumar (25), Satish Kumar (23) and Suresh Kumar (27 ) — are from Tondiarpet.
