Specialist British Royal Navy divers are to be drafted in to identify the mystery vessel inn the depths of the Foyle.
A number of theories have been put forward since sonar picked up the wreck on the river bed - prompting a multi agency meeting in Derry yesterday afternoon.
Among those to attend were representatives from the Northern Ireland Environment Agency, the British Royal Navy, PSNI and the Harbour Commission.
The north’s environment minister Alex Attwood says the mystery could be solved within ten days once further surveillance work is carried out.
“There has been a lot of speculation and it is probably best that I don’t fuel it I am not going to have a situation where we are sending out our own NIEA divers who don’t have the skills and they accept that they don’t have the skills.
“They are great – very skilful people – but not at dealing with munitions or ordinance. Once we can identify what is lying on the river bed, opportunities may arise. There is massive interest in what is there but at this stage we don’t know.
“There are risks associated with the site. This requires a specialist team to conduct a dive on the site. I have requested the assistance of specialist Navy divers to undertake this task and I anticipate a positive response.”
