The police command in Anambra has said it is well-prepared and ready for the February 25 and March 11 elections.
The police confirmed the attack but could not immediately provide details on the details of the who were freed.
The deceased had visited with three friends and drowned while swimming at the Olympic-size pool.
The team recently came under public scrutiny following allegations of extortion, intimidation and rights abuses made against its members.
Governor Wike said a White Paper on the report would be produced next week during the state executive council meeting.
