TENB Y school pupils watching BBC1 after school on Friday over the past two weeks might have spotted a familiar face - or heard a familiar voice emerging from a post box!

Greenhill pupil Sita Thomas is an actor and presenter on the popular children's television programme Stitch Up, which is currently being repeated on BBC1 on Friday afternoons at 4.55 pm. Stitch Up is a hidden camera show in which a team of six young presenters cause mayhem and mischief by playing gentle pranks on unsuspecting members of the public.

Sita joined the show for series three, which first appeared on CBBC in 2004. She and fellow presenter Adam Selkirk-Brown were selected from hundreds of hopeful young people after several auditions in London.

The programme's producer, Jeremy Daldry, said: "We filmed all the contestants, then watched them on screen to see whose personalities came over best. Sita fits onto the show's dynamic, and her work is excellent".

This Friday Sita will appear in various guises, including a yodeller, a very enthusiastic person, and inside a postbox. In a future episode she presents the show's finale big stitch up hidden inside a large box at Hemel Hempstead Garden Centre pretending to be a rare and exotic but toxic plant.

Sita has had a string of successes this year. She has been awarded a drama scholarship for A level study to a prestigious specialist sixth form college; she has been selected to join both the National Youth Theatre of Wales and National Youth Dance Wales; and she has achieved distinctions in both her LAMDA solo acting gold medal/grade 8 examination and in her RAD grade 7 ballet exam. Sita trains locally with LAMDA teacher Gill Rawlins, with On Your Toes School of Dance, and with the Torch Youth Theatre, and attends screen acting classes with Peter Wooldridge at the Workshop in Cardiff.
