A man from Northern Ireland has been arrested in connection with the Essex Lorry tragedy.
Police say the man is 23 years old.
He was arrested on the M40 in Buckinghamshire early this morning.
He's being held on suspicion of conspiracy to traffic people and assist unlawful immigration.

Last month 39 people were found dead in a container shipped from Zeebrugge in Belgium to Essex in the UK.
All 39 were from Vietnam.
This isn't the first arrest of someone from Northern Ireland in connection with this investigation.
25-year-old Maurice Robinson from Armagh has been charged with 39 counts of manslaughter as well as other offences.
22-year-old Eamon Harrison from Down faces similar charges and police have started extradition proceedings to bring him to the UK.
Detectives have also urged the Hughes brother - Ronan and Christopher from Armagh - to hand themselves in for questioning.
They're said to have links with the road haulage and shipping industries.
