Police in Vietnam said Sunday that they have taken DNA samples from citizens who believe they may be related to some of the 39 victims who were found dead in the back of a truck near London last week.
British police are still struggling to identify the bodies, which were discovered on Wednesday in Grays, Essex, roughly 32 km (20 miles) from central London.
Police in the central Vietnamese province of Nghe An took samples, including hair and nails, from people in order to try and identify the victims, the VNExpress news website said.
Up to 24 Vietnamese families had declared their missing relatives to authorities over the weekend, the website reported.

British and Vietnamese authorities are now working together to identify four of the 39 people found dead with the former sending the latter dossiers.
Vietnam's government website quoted Deputy Foreign Minister Bui Thanh Son as saying the Ministry of Public Security had received files, seeking "verification coordination."
Son said: "The Ministry of Foreign Affairs is developing dossiers of possible victims, but until now there have been no grounds to confirm Vietnamese nationals are among the victims."
The driver has been charged with manslaughter and conspiracy to traffic people.
Authorities said 25-year-old Maurice R. from Northern Ireland faces "39 counts of manslaughter, conspiracy to traffic people, conspiracy to assist unlawful immigration and money laundering."
