A 16-year-old boy has been arrested this morning in connection with an incident where two people rode around Arnold town centre on a moped wielding a knife.
The two people chased a 17-year-old boy during the incident in Front Street at around 3.30pm on Wednesday (14 November).
The boy who has been arrested is currently being questioned by detectives on suspicion of attempting to cause grievous bodily harm.
Officers also recovered a moped in Top Valley yesterday in connection with the investigation.
Detective Inspector Kim Binns, who is leading the investigation, said: "I would like to thank everyone who has got in touch so far with information. Clearly the community of Arnold won't stand for incidents like this, and neither will we.
"However the investigation is still continuing and I would urge anyone who has information and hasn't come forward yet to please get in touch on 101, quoting incident number 565 of 14 November, or on Crimestoppers anonymously on 0800 555 111."
