Speaking after sentencing, officer in the case, DI Steve Dowson said: “This was a long and complicated investigation involving a number of Detectives from the local CID teams.
“Clearly this was a terrifying ordeal for the victims which will stay with them for a very long time.
“This case should demonstrate to the people of Lancashire that we will fully investigate any offences of this nature and will leave no stone unturned in our efforts to catch the people responsible. My message to criminals who come into Lancashire to commit this type of crime is that you will be arrested, convicted and sent to prison.”
