Thames Valley Police is appealing for information regarding Sana Sejad and Amna Hassan, both 15, from Slough.

They were last seen at Sainsbury’s supermarket in Farnham Road at about 8.30am yesterday (18/5).

Police believe that they then travelled to Tesco in Bath Road, next to the railway station.

Sana is slim, about 5ft 6ins, has very long straight black hair, brown eyes and usually wears glasses.

Amna is slim, about 5ft 4ins, has very long straight black hair with blonde streaks and brown eyes.

Police believe that the pair might be heading to or are already in Southall in West London.

Det Insp Stuart Brangwin of Force CID based at Maidenhead police station said: “If Sana and Amna are reading this then please make contact with your family or the police by calling 101 so we know that you are safe and well. Neither of you are in trouble but your loved ones are concerned for your safety so please make contact as soon as you can.

“We believe that the pair may have travelled to or plan to travel to Southall in west London, so I would ask commuters and those using public transport to look out for the two girls.

“This is out of character for both girls so we are very concerned for their welfare.

“If anyone has any information about Sana and Amna’s whereabouts then please contact the Force via 101 and quote reference number 373 (18/5).
