Five Indian seafarers have been released following their kidnapping from a Greek tanker off Nigeria in April.

India's ministry of external affairs said the crew were due to return to Mumbai on Monday.

The men spent more than 70 days in the hands of the gunmen after being seized on 19 April from the 3,075-dwt Apecus (built 1973) off Bonny Island.

It was originally reported that six seafarers had been abducted.

"Our seafarers on Apecus - Sudeep, Chirag, Avinash, Ankit and Ravi, who have been released from captivity in Nigeria, are returning to Mumbai tomorrow," TS Tirumurti, secretary of economic relations for the ministry was cited by DNA India as saying.

Minister of state for shipping Mansukh Mandaviya added: "I am happy to share that due to sustained efforts of various stakeholders including Ministry of Shipping, the Directorate General of Shipping and the High Commission of India, Abujam, Nigeria, the kidnapped Indian seafarers were successfully released and have reached the safe custody of the authorities."

Apecus is owned by Tomazos Shipping and managed by Petrogress subsidiary Petronav Carriers.
