The University of York student’s mum, Amanda Parker, is desperate to speak to anyone who was with them that night and spoke to them about their plans.As Harvey is autistic, she says they can often misread certain social situations, which could make them particularly vulnerable.

The music student’s phone has been unresponsive since going missing and they have not posted anything on social media. Amanda told Metro.co.uk: ‘Just before we went to bed Harvey came back and was really upbeat and very positive about the concert and had a good time.’She says Harvey got changed at their home in Waterloo, central London, before heading back out.When they didn’t come back on Friday morning, she assumed Harvey had gone to work at the Theatre Royal Stratford East.
