A former contractor, who was among those questioned by police in connection with the detection of explosive material on a Kingfisher aircraft last month, allegedly committed suicide at his residence at Valiyathara near Thiruvananthapuram.
The body of Sunil Lawrence (25) was found hanging at his residence on Friday morning, police said.
He was employed by the same company of which a staffer, Rajasekharan Nair, was arrested and remanded on March 28
