Although his charge is one of GBH with intent, he has no previous convictions and as a good family background. The judge as given him bail whilst awaiting sentencing. These things normally go for you upon sentencing. If the judge thought he was a danger to the public he would have sent him into custody whilst awaiting his sentence.
Although there is a big outcry about IPPs at the moment and judges were issuing them to this type of, and i know (from experience) that this charge carries an IPP, judges have been told that they are only to issue these IPPs now if they find that the person they are sentencing is deemed a danger to public. It was supposed to be run along the same lines as "3 strikes and your out".
There are a lot of changes going on with IPPs because of the judges issueing them willy nilly it has caused considerable overcrowding in the prisons, causing prisoners to be released early. So judges are being warned about this on sentencing.
Someone close to me was sentenced and we were told by his barrister that he would receive an IPP. He had a few GOOD character references, one being mine and his barrister and an excellent probation report (this bodes well) saying he was low risk of re-offending - upon this he received 2 1/2 years, serving 15 months (he will get an early release ddate because of the overcrowding situation - but only 18 days and he has to be on enhanced regime).
So - at the moment the IPPs are just being picked out of the air by some judges and others are staying away from them. I think it depends on the judge and the probation report as to the charge.
I know people in prison that have received IPPs for next to nothing, but they are re-offenders and people who have been charged on a section 18 and 20 and not received one.
