A police officer has asked the public to help her locate her sister, who disappeared from their house at the Police Staff Training College in Loresho on Tuesday.

Inspector Teresia Wambui says her sister, Margaret Njoki Kirungui, 42, who has been suffering from depression, left the house at 3am and had not been seen since.

“I have been living with her at my house, but she woke up at night and walked out of the gate and has not come back,” Inspector Wambui said.

She said she has looked for her in several places but in vain.

At the time of her disappearance, Ms Njoki, who is tall and dark, was wearing a black pair of trousers and was covering herself with a blue Kikoi with white stripes.

Her disappearance has been reported at the Spring Valley and Kabete police stations.
