Royal Bank of Scotland (RBS) and the City of London Police have signed an agreement which will see the former provide free training and advice on financial crime.Last week, RBS set aside £400m to cover potential settlements for manipulating currency markets and warned further sanctions for past misconduct would continue to hinder its profits.According to a Financial Times report, the deal between RBS and the police force will be kept separate from the ongoing investigations into the bank and that RBS employees will not be involved in police operations.RBS shares were down 2.16% to 379.60p at 16:25 on Monday.
