A young man of approx age 17, asked for the time. I gave him the time promptly and walked off, he followed me and asked to be my friend I walked off ignoring him, sensing that this is odd. He continued to follow me, grab my arm and show me his phone that showed some porn playing. Specifically, a women touching herself.
The guy was wearing a blue long sleeve top carrying a rucksack. When I began to shout at him, he ran as fast as he could in the opposite direction.
