The Attorney General's Office has confirmed it is looking into the four-and-a-half -year sentence given to Lewis Gill, 20, after pleading guilty to manslaughter for a punch that killed a 40-year-old man.
A statement said:
The Attorney General’s Office has received a number of requests to look at the sentence given to Lewis Gill.
If a sentence given in a Crown Court appears to be very low, or unduly lenient, anyone can ask the Attorney General to examine the sentence, within 28 days of sentencing.
This process has now started. We have asked the CPS to send us more information this case.
