A care assistant who worked at a unit where a teenager drowned in a bath is to appear in court tomorrow charged with defrauding Southern Health Foundation Trust of more than £250,000.

Milca Mugo will appear before Oxford magistrates charged with obtaining a pecuniary advantage of £253,000 between 2005 and 2016 despite not being eligible to work in the UK.

It is alleged her identity came to light during a Disclosure and Barring Services check in March 2016.

Ms Mugo worked as a mental health care assistant at Slade House, the residential unit run by Southern Health FT where Connor Sparrowhawk drowned in a bath following an epileptic fit in 2013. An inquest jury ruled serious failings and neglect had contributed to his death.

Slade House was closed in 2014 and the trust is facing prosecution by the Health and Safety Executive in connection with Mr Sparrowhawk’s death under the Health and Safety at Work Act 1974.

The unit was run by the Oxfordshire Learning Disability Trust – also known as the Ridgeway Partnership – until it was taken over by Southern Health in 2012.
