Two further people have been arrested by police investigating the deaths of 19 cockle pickers at Morecambe Bay.
It brings the total number of arrested people to seven. The five men and two women are being quizzed about whether they were involved in Friday's tragedy.
The people who died were from China and police believe they may have been illegally brought to this country by 'gangmasters'.
The workers were killed by powerful tides while looking for the cockles.
