Watch the CCTV

The images show Jeshma Raithatha, 17, shopping in north-west London, about an hour before she was raped and stabbed to death as she walked home.

She is seen queuing to buy a top in Primark on Wembley High Road at about 1420 BST on 16 May.

About an hour later she is thought to have been attacked by a stranger on a footpath in Sudbury Hill, west London.

The pictures show Jeshma, casually dressed, shopping in Wembley just after 1400 BST on the day she disappeared.

She had been to school - Claremont High in Kenton, north-west London - but as an A-Level student due to take her first exam the following week, she did not have to stay all day.

Cameras recorded her buying a top in Primark, then a candle in Poundcity, before she caught the 92 bus back to Sudbury Hill.

She arrived at about 1500 BST and is thought to have begun walking home down a road by a recreation ground near the David Lloyd sports centre.

She would have taken a footpath which cuts through a wooded area, towards the Wood End estate.

Police think she was grabbed by a stranger, taken to a secluded wooded "den", raped and stabbed three times through the heart.

Her partially-clothed body was found by police search teams eight days later.

Police are still looking for a man who lived near Jeshma but has gone missing from his home.
