Four people have been left terrified after an aggravated burglary in Banbury.
At 10.50 last Thursday evening a teenage boy answered the door of a house in Sydenham Close in Adderbury.
On the other side were three masked men who forced their way inside.
The boy beat one with a baseball bat, but dropped it when he realised another had a knife.
The boy's mum was then assaulted and jewellery taken from her.
Two girls who were also in the house at the time were taken into a bedroom but unharmed.
The suspects are believed to be black men, of muscular build wearing balaclavas - although one had a distinctive orange high vis jacket.
Investigating officer Detective Constable Grahame Lea, of Force CID at Banbury police station, said: “I am appealing for any witnesses who were in the area at around 10.50pm on Thursday who may have seen the men in or around Sydenham Close.
“At least one of the men was wearing a distinctive high visibility tabard.
“In addition, I’m appealing for a taxi driver who dropped off a person in the area of Sydenham Close and would have seen the offenders to contact police.
“Likewise, I am asking to anybody who has CCTV covering Aynho Road and up to Sydenham Close to contact us.
“This was a terrifying ordeal for the victims and we are keen to identify any leads that will assist in identifying those responsible.”
