Detectives have launched a dramatic new investigation into allegations that Labour peer Lord Janner sexually abused a teenage boy.
Officers will also look at whether he engineered a cover-up when police first received the complaint 24 years ago.
The surprise development will pile more pressure on the Crown Prosecution Service in England over its controversial decision not to bring charges against the former Labour MP because he has dementia.
The new police investigation is being carried out in Scotland, which has its own legal system, raising the possibility that the peer could still be prosecuted north of the border.
Janner, 86, stands accused of abusing vulnerable youngsters at care homes in his former Leicester constituency between 1969 and 1988.
