A woman has been robbed at knifepoint in a Brighton car park.
The attack happened in the NCP car park in Blackman Street just after 5pm on Thursday afternoon.
She was in her Volkswagen Polo preparing to drive away when a man got into the back of her car.
He held a knife to her face and said: “I want money now.”
She handed over her purse and he then demanded her gold necklace, saying: “I need more. I want jewellery.”
She gave him the necklace and he got out of the car and left, saying “sorry” as he fled.
Sussex Police said that the knifeman was described as white, aged 21-24, about 5ft 8in tall and of slim build.
He had a pale face and jet black hair with a long fringe which came to just above his eyebrows.
He was wearing a dark blue plaid/checked jacket, dark trousers and may have had a hat. He spoke with an accent described as East European.
The knife was described as a kitchen knife about 9in long.
Shortly before the attack, the woman had a conversation at the pay machine with a man who was having trouble paying for his ticket.
Detective Constable Sapna Patel, from Brighton CID, said: “This was a desperate and unprovoked attack that was extremely distressing for the victim.
“I would particularly like to hear from the man at the pay machine and anyone else who witnessed the incident or saw someone matching the description of the offender in the area around that time.”
Witnesses are urged to call 0845 6070999.
