A man whose surprise arrest at Southwark station in July caused the station to be closed has revealed what happened.
Two months later The Guardian has published an account of events that night by David Mery who was arrested inside the station.
David, who works nearby, entered the station at 7.21pm on his way to Bond Street. As a train entered the north bound plaform he was surrounded by police officers who removed his rucksack.
"They take off the handcuffs and start giving me back my possessions: my purse, keys, some papers." writes David. "Another police officer says that this is not proper. I am handcuffed again. A police van arrives and I am told that I will wait in the back. After about five minutes, a police officer formally arrests me."
Arrested for suspicious behaviour and public nuisance, David was taken to Walworth police station. After his flat had been searched he was bailed and released at 4.30am.
Afterwards David Mery hired a solicitor who was with him at the end of August when he was informed that charges had been dropped. During this five minute meeting at 9am he was told that items removed from his flat would be returned later.
In his front page article, David Mery expresses concern that the police are entitled to keep his fingerprints and DNA samples taken on the day of his arrest although he is an innocent member of the public.
