Probe launched into 24-year-old's death at Walsall Manor Hospital

Mark Ankrett died at the hospital in November 2013 after suffering a bleed to the brain – but his care over six years led his mother Tracey to make two official complaints.

Among the concerns, his family claim he was refused an MRI scan despite their wishes.

The family of the 24-year-old, from Bloxwich, have been waiting for an independent external review into their son's care to start – at the third attempt.

Now, London based firm Verita have opened an investigation into what happened and Mr Ankrett's mother has claimed she will get the truth.

The investigation will look into the care Mr Ankrett received at both the Manor Hospital and the Queen Elizabeth Hospital in Birmingham.

Mr Ankrett, who was diagnosed with epilepsy as a youngster, would regularly suffer seizures which would require hospital treatment.

In 2007, doctors found a five-centimetre growth – called an arteriovenous malformation – on his brain.

It carried an increased risk of a stroke or brain haemorrhage.

Because of the condition he had to stop playing sport, stop learning how to drive, and could not continue his bricklaying course at South Staffordshire College.

After regularly having appointments with the hospital's neurology department every six months, in May 2011 they stopped without explanation.

Mr Ankrett was in and out of hospital in the following years but there are claims that notes on his condition were not recorded by a neurologist or shared between departments.

In November 2012, Mr Ankrett suffered five seizures in a day, and his family believe that this is when the bleed on his brain began.

His family claim each time Mr Ankrett was admitted to hospital and seen by medics, they refused to perform an MRI scan despite their wishes.

In November 2013, Mr Ankrett collapsed and was admitted back to Manor Hospital – just three days after he had received treatment at Queen Elizabeth Hospital after suffering another seizure.

Three hours after being admitted, Mr Ankrett's parents were told he had a massive bleed on his brain and he was being put on life support.

An hour later his family were told they would turning off the life support machine.

Two years ago, Mark's mother Tracey launched an online petition calling for an 'open and honest' investigation into what happened during her sons time at the Manor.

More than 1,000 people have since signed the petition on change.org.

In an update on the web page, Tracey wrote: "An external investigation into Marks care has now begun by a London based firm 'Verita, Improvement Through Investigation'.

"The investigation is a joint venture which will include care and management of Marks illness from both 'Walsall Manor Hospital' and 'Queen Elizabeth Hospital Birmingham'.

"The petition will continue until we are satisfied that the trust has been fully 'Open and Honest' about the care Mark received.

"Thank you for your on going support."
