A 'TEEN' was told to 'watch his language' as he was arrested outside McDonald's in Worcester city centre. 

The young man, who appeared to be aged 17 to 18 by witnesses, was given a warning by an officer as he shouted and swore at the police while on the ground and in handcuffs. 

An eyewitness said he saw the teen beating up another boy on a bus, but just seconds after he called 999, he spotted and chased down two police officers to alert them to what was going on.  

He said at around 3.45pm yesterday (Saturday, September 28), he was walking across from the Horn and Trumpet pub when he heard shouting coming from outside McDonald's in The Cross.

He added seconds later he then saw a young boy running past him and another pursuing him just behind.

The eyewitness told the Worcester News: "It was lucky I spotted the two police officers as they were able to catch the youngster. 

"I haven't really seen fights in Worcester before, it was quite a shock."

The eyewitness sent the Worcester News a video of the arrest, during which you can hear the teenager swearing and shouting at one of the officers. 

The police officer can be heard telling him to watch his language before arresting him for assault.
