Four people were arrested after the attack
A man has been treated in hospital after being stabbed following a confrontation with a young girl wearing a clown mask.
Four people from Southsea in Portsmouth were arrested after the attack in Sedgley Close at 8.30pm last night.
The 34-year-old woman, two 18-year-old men and a 17-year-old boy are being held in police custody.
The 28-year-old victim has now been discharged from hospital.
Detective Inspector Linda Howard from Hampshire Constabulary said: "It has been reported that this incident was sparked by an earlier altercation involving a child wearing a clown mask.
"This is one of the lines of inquiry being followed."
She added: "But at this time we would ask people not to speculate further and instead contact the investigation team if you have any information about what happened."
Childline's UK branch reported an influx of calls in the wake of a series of international clown sightings. Clows caused 500 children to contact the NSPCC's service in just three weeks, with Childine providing 84 clown-related counselling sessions on one day alone.
An NSPCC spokesperson said: “Wearing spooky fancy dress for Halloween is a time-honoured tradition, but we fear the recent creepy clown craze could see Halloween used as an opportunity to molest, intimate or harm children. Creepy clowns are all trick and no treat; those dressing up with the intention of threatening children need to be aware that they could be breaking the law – particularly if they are carrying weapons."
