Customs officials on Wednesday arrested a man at the Chennai airport with a suitcase containing five venomous snakes.
Airport sources said the arrested Mohammed Azarudin, who arrived by a Thai Airways flight, told the Customs officials that one of his friends in Thaliand gave the suitcase to him with a request to hand it over to a person in Chennai.
He said he was given Rs 10,000 for carrying the suitcase and was unaware of the contents in it.
Customs officials were investigating how Azaruddin managed to board the flight from Thailand and cleared the security checks there.
The suitcase was later handed over to Forest Department, the sources said.
