A man and woman were the victims of a robbery in an alleyway close to the Tithe Barn in Wellingborough during the early hours of Friday, July 27.
Between 2am and 2.30am, the pair were walking past the Tithe Barn on their way home following a night out.
They were approached by two offenders who threatened them and stole their mobile phones and tobacco.
The first offender was white, aged 18 to 20, of stocky build with short fair hair. He may have been eastern European and wore a blue Adidas hoody and possibly a turquoise t-shirt.
The second offender was described as mixed race of similar age, slim build and with short curly black hair. He wore a red top.
It is believed the offenders may have been involved in a minor altercation outside Fever nightclub in Wellingborough earlier on in the evening.
