The first burglary happened between 11.30am and 10.30pm at a property in Waverley Avenue, Kidlington, where burglars forced their way into the property and stole cash and jewellery.

The next burglary was at Price Close in Bicester, shortly before 6.55pm, where burglars forced their way into a house through a rear patio door and stole jewellery, including a string of pearls and a silver watch.

Witnesses saw two men leaving the property. They are both described as white and around 5ft10ins tall.

The first man was wearing a green quilted jacket, blue jeans and white trainers. The other man was wearing a black baseball cap, a dark-coloured or black top, blue jeans and white trainers.

The third incident happened at 7.10am at a property in Graham Road, Bicester. A 77-year-old man returned home and heard some noises coming from the rear of his house. When he went to investigate, he discovered his patio door had been smashed, but no one was there.
