A 23-year-old man was arrested in the Sussex coast town by police investigating the Manchester bombing.
A man who lived in a flat raided by counter-terror police in Shoreham-by-Sea, Sussex, was a Libyan training to be a pilot, a hairdresser said.
Violet Mainda, who cuts the hair of the man who lives in the flat, described her client as "a very nice bloke".
Ms Mainda, who owns a hairdressing salon below the flat, said he came into the salon a few times to get his hair cut.
A 23-year-old man was held on suspicion of terror offences at an address in Shoreham in the early hours of Monday morning, Greater Manchester Police said.
