The Devon police department caused a major panic among parents after they took an unusual step of sending letters through school children,

The detectives went on to say that they have arrested a 19-year old in connection with the case while over 20 alleged victims were interviewed. The police added that they are looking into sex assaults in the region over a period of three years and said that the perpetrators could be a gang of youths in their late teens.
“We are treating this investigation very seriously. We are looking at other people and further arrests may be made in the coming days and weeks. We are not dealing with individuals that are grabbing children off the streets. Each of the children is known to the offenders”, senior Investigating Officer, Det Insp Simon Snell said.
