Problems with DNA evidence have delayed the prosecution of suspects over the murder of a Red Cross worker in Sri Lanka in 2011, British officials said.
Khuram Shaikh, 32, from Milnrow, Rochdale, Greater Manchester, was shot and stabbed on Christmas Day 2011.
Eight people, including a Sri Lankan politician, were arrested and bailed in November. They all denied the charges.
The British High Commission in Colombo said the 18-month delay was “not a good message to tourists”.
The Sri Lanka High Commission said the “Government Analyst’s report relating to DNA evidence is awaited and all arrangements have been made to commence proceedings upon receipt of the same”.
