He explained the case against him was dropped within a week after CCTV evidence proved he was not in the area at the time of the alleged attack.
He said the false allegation has also cost him about £800 in lost work and staying in hotels while the case was being investigated.
Detective Chief Inspector Carwyn Hughes said: “Police were already investigating a number of incidents in the Kemp Town area when this allegation was made.
“As in all cases we took this report very seriously and were quick to respond.
“On launching an extensive investigation we quickly concluded that this offence did not take place…Well, I suppose a week is considered ‘quick’ in police circles…
But a pity you didn’t reach this conclusion before you’d arrested, swabbed and interrogated the poor man, eh?
… and aside from raising unnecessary anxiety and alarm, many hours were wasted that could have been put to better use investigating genuine reports of crime.”Yes. Indeed. Think of all the Twitter users you could have been arresting instead.
“I would like to stress that this will not affect in any way our response to reports of sexual offences and I would urge anyone who is a victim to contact us, even if the incident happened a while ago. ”Translation: “We don’t learn any lessons. Because we never suffer when we get these sort of things wrong.”
