This appears strange, The solicitors should not have access to any of the bank accounts or details of any investors involved in this until the police have finished their investigation, the police will most likely have ask the banks to cease all correspondence with anyone other than them until the investigation is complete, also as far as i'm aware the police have not pressed charges or concluded that a crime has been committed as yet, if PP are making refunds it can only be on the basis that I4Y were never properly registered as its common knowledge on the FCA website. i can't see how the solicitors can authorise anything while an active police investigation is ongoing.
