I have just got back from speaking to the police about the incidents.
They did not know about them as they haven't been reported. They will put more patrols in the area and have asked that if anything happens to anyone they need to call 155 and the police will come to the location immediately. They have also said that however distressing the situation is, they need descriptions and registration numbers of vehicles involved. Also a report to the police needs to be made.
They were genuinely concerned about what has happened and want to catch the man or men that are doing this, but they need the reports, phone calls, descriptions etc to help them.
