Tirunelveli Junction Railway station Manager (in charge) Sivasankaranarayanan had complained to police after he received a registered post yesterday.
The letter reportedly stated that Nellai express bound for Tirunelveli would not arrive on December 24 as it would meet with an accident similar to the recent Kanpur Railway accident.
The man was traced and on being questioned admitted to sending the letter and that he was depressed as his relatives had destroyed some documents relating to his property, police said.
