India is on the watch for a "toxic tanker" that Bangladesh chased away from its shipbreaking beaches in May.

The Department of Border Management of India's Ministry of Home Affairs has warned that the Gujarat state government that the arrival of the 60,500-dwt dirty panamax tanker J Nat (built 1983) is "imminent".

"It has also been stated that the vessel is considered to be an environmental threat with long run ramifications on security," wrote coastal security commandant HC Upadhyay in the message to Gujarat officials, dated earlier this month.
