DETECTIVES investigating the deaths of 39 people whose bodies were found in Grays last week are releasing details of two Armagh brothers they want to speak to.
Ronan Hughes, 40, and his brother Christopher, who is 34, are wanted on suspicion of manslaughter and human trafficking.
Ronan Hughes, who also goes by the name Rowan, and Christopher have links to both Northern Ireland and the Irish Republic.
Detective Chief Superintendent Stuart Hooper, who is leading the investigation, said: “Finding and speaking to the Hughes brothers is crucial to our investigation.
“At this time we believe they are in Northern Ireland but they also have links to the Irish Republic.
“If you know where they are or have any information about their whereabouts I need you to call my team.
“This is a case where 39 men and women have tragically died and support from the community is going to be vital to help bring those responsible to justice.
“You may think the piece of information might be insignificant but even the smallest detail could be vital so please contact my officers on 101 or online at: the UK Police Major Incident Public Reporting site
“I appreciate you may not want to speak to the police so you can also contact Crimestoppers 100 per cent anonymously on 0800 555 111.”
