Three people arrested in connection with the deaths of 39 people found in a lorry trailer in Grays, Essex, have been released on bail.

Essex Police said a man and woman, both 38, from Warrington, were arrested in Cheshire on Friday and a 46-year-old man from Northern Ireland was arrested at Stansted Airport later the same day.

All three had been questioned on suspicion of manslaughter and conspiracy to traffic people.

On Sunday police said the man and woman from Warrington, named locally as haulage boss Thomas Maher and his wife Joanna, were released on bail until November 11.

The Northern Ireland man has been bailed until November 13.

It comes as officers investigate whether the container in which 39 migrants were found frozen to death in Essex was part of a convoy of three lorries.
