The joint opposition had said that at least one underworld member was seen with Fonseka as part of his security detail recently.
Speaking to reporters today, Fonseka said that the allegation was false.
He said that he does not require underworld members to be part of his security detail.
A media report had earlier quoted a senior police officer as saying that five underworld leaders had been appointed as the private bodyguards of a Minister.
The media report said that the Police were unable to arrest the five underworld leaders as they had the support of the Minister.
Prime Minister Ranil Wickremesinghe had informed Parliament recently that an investigation has been launched into the media report.
Wickremesinghe said that the media report did not quote the name of the Police officer who gave the details so the newspaper was asked to furnish information related to the allegation. (Colombo Gazette)
