PC Marek Jaworski, from Basildon Police, said: "The two men were walking along Timberlog Lane when this group of about 20 people surrounded them and started attacking the victim.
"He was kicked twice in the back and once in the head and face, which caused reddening and bruising.
"Fortunately the blows did not pierce the skin. "The 18-year-old then managed to escape from the gang and run off.
"Apparently they don't know who they were, which makes it all the more worrying. It could have been that members of the gang were egging each other on to attack passers-by."Ooh! That’s not the message you should send! It should be things like ‘isolated incident’ and ‘no reason to believe members of the public are at risk’.
You won’t get far telling the truth.
