More arrests in connection to the Manchester bombing.

A 23-year-old man, thought to be Libyan, has been taken into custody at Shoreham by Sea, in Sussex, more than 400 kilometres from Manchester.

UK correspondent Gavin Gray told Nadine Higgins the arrested man's occupation is of particular interest.

"He's a commercial pilot and it is said that he runs an online market place for Libyans from his West Sussex home," he said.

Gray said a 19-year-old man was also arrested in Manchester, while British police have released a photo of bomber Salman Albedi, showing him wheeling a blue suitcase on the day of the bombing.
