Mr Flame had taken up to 10 MDMA capsules in addition to smoking cannabis and drinking alcohol before he bashed Mr Anderson, the jury has heard.

Mr Buchert said he "sized up" to Mr Flame but decided not to intervene because he was bigger than him and didn't appear "coherent".

Nadia Khalil, who spent part of the night with the pair, said Mr Flame became "closed off" at her house.

Mr Anderson also followed and tried to help Mr Flame.
