The Wales international midfielder, who completed his much-wanted move to Ewood Park on Wednesday, is considered 'public enemy number one in Birmingham' according to Sullivan.
Therefore, Sullivan told the Daily Mirror, Blues requested an additional £100,000 on top of the £3million transfer fee Rovers paid for Savage to foot the police bill that would be incurred if the player was to play for Rovers when they visit St Andrew's for a Premier League encounter on 30th April.
