Stuart Campbell was arrested in August on "suspicion of harassment and malicious communications". He was subsequently bailed pending further enquiries.
It is understood that a woman in her 30s reported Mr Campbell at a south London police station, where she alleged the harassment had taken place over a two year period.
The Metropolitan Police issued a statement saying Police in Southwark had investigated the allegations and that Stuart Campbell has been informed that he is released with no further action.
