On the day of his death, Benjamin Walter took Geoffrey Reed to the Nationwide Building Society to withdraw money out of his account. When they returned to the flat it was the last time Mr Reed was seen alive.
The CPS said: "While it is true that Mr Reed was a convicted sex offender this cannot justify the brutal attack on him and from which he died.”
