The National Crime Agency is working with its partners over claims they arrested the wrong person in a people smuggling operation.

Mered Medhanie, known as 'The General', was extradited to Italy on Tuesday after being accused of being behind an international smuggling network.

Prosecutors allege Medhanie was responsible for the deaths of 359 migrants who drowned after their boat sank off the Italian island of Lampedusa in 2013.

However there are suggestions they have arrested the wrong man, in a case of mistaken identity.

Media reports say the man sent to Italy was in fact Medhanie Tesfamariam Kidane, a 27-year-old refugee.

An NCA spokesman said: "This is a complex mutli partner operation and it is too soon to speculate about these claims".

He said the NCA is confident in its intelligence gathering process and is "liaising with our partners".

Italian police released a video on Wednesday purportedly showing the moment Mr Medhanie was led away in a convoy of police vehicles after landing in Italy.

He was arrested in the Sudanese capital Khartoum in May, following an operation that involved Britain's National Crime Agency and GCHQ, as well as Italian and Sudanese authorities.
