Last photo of woman, 33, who vanished while walking home

The last picture of a woman from the day she vanished has emerged as police investigate the circumstances around her mysterious disappearance.

Sarah Everard, 33, had been at a friend's house in Clapham, south London, on March 3 in the hours before she went missing.

Metropolitan Police said in a statement she had left her friend's home about 9pm (local time) through a back gate and began the 50-minute walk home.

However police say it is unclear whether she ever made it.

CCTV footage captured on the night she went missing shows her walking and talking on the phone while wearing a green jacket, beanie and face mask.

Authorities hope the image may trigger somebody to come forward with information.

"Sarah's disappearance is completely out of character and understandably her family and friends are incredibly worried," Detective Chief Inspector Ian Kenward, from the Central South Public Protection Team, said.

"We are also growing increasingly concerned for her welfare and have officers working round the clock to try and find her.

"I would ask anybody who was in the Clapham Common area on Wednesday night to think about whether you saw Sarah or any suspicious activity around the time of her disappearance."

Women warned 'not to go out alone'

According to The Sun, Met Police officers have been knocking on doors in south London warning women to be careful when they go out alone due to fears of a kidnapper in the area.

"I was told to be more careful because I live on my own," one woman said.

"The police came round yesterday and said to be careful.

"I don't want to leave the house at the moment. You don't know what happened.

"It makes me very worried. I just can't believe it."

One resident said police advised women in the area to catch Ubers rather than walk, while another claimed she had not been out alone since Sarah disappeared.

Family makes desperate plea

Sarah's family said they grew more worried about the woman as each day went by.

"She is always in regular contact with us and with her friends and it is totally out of character for her to disappear like this," her family said in a statement.

"We long to see her and want nothing more than for her to be found safe and well.

"We are so grateful to the police and all our friends for all they are doing. We are desperate for news and if anyone knows anything about what has happened to her, we would urge you to please come forward and speak to the police."
