mutt in the mid-80s, a work colleague was sent to prison for 2 weeks, for a drink-driving offence. I seem to remember that you were "tried" the morning after the offence and taken directly to prison. This was the "old" prison, at the end of al Satwa Road. The next thing we knew was that he was in the Rashid hospital, in a coma. He stayed there for several months, before he was medivac'd to the UK. He eventually received several hundred thousand pounds in "compensation" from the UAE authorities, although responsibility for what happened in prison was never officially accepted. He eventually emerged from the coma, but was never able to work again, and died in his 30s.
I hope things have changed in 20 years!
