BELFAST The arrest of Sinn Fein leader Gerry Adams is a deliberate attempt by unidentified "dark" forces to undermine the peace process, Northern Ireland's Deputy First Minister Martin McGuinness said on Thursday.
McGuinness, also a member of Sinn Fein, said the Police Service of Northern Ireland contained a "dark side" which was "maliciously and vehemently hostile to the peace process".
"I know that we've seen that dark side flex its muscles in the course of the last couple of days," he said.
"I view his (Adams') arrest as a deliberate attempt to influence the outcome of the elections that are due to take place in three weeks' time, north and south on this island."
