A lawyer at a top legal firm has been accused of subjecting a train passenger to a 90 minute 'torrent of abuse' after the other man asked him to turn down the volume on his phone.
Thomas Longstaff, 29, who is an associate at Linklaters in the City of London, was linked to an appeal by the British Transport Police.
They claim a man - alleged to be Mr Longstaff - became aggressive while travelling on a train from London King's Cross to Leeds on December 9.
It is believed a fellow passenger asked him to turn down the volume on his smartphone while he was playing games.

Police added that the man 'started verbally abusing the victim' which made him feel 'uncomfortable' and 'threatened'.
Legal gossip website Roll on Friday identified the man in the appeal as looking like Mr Longstaff after a lawyer who worked with him at another firm recognised him.
The BTP is aware and today confirmed that a man has contacted them and is helping them with enquiries.
Mr Longstaff became an associated at Linklaters - which has 2,164 lawyers and is one of the biggest international law firms in London - in October last year.
The firm received revenues of £1.31billion in 2016 and it has 29 offices in 20 different countries.
Mr Longstaff, who graduated at the University of Law in Leeds, trained at DLA Piper, according to Roll on Friday.
MailOnline has contacted him and Linklaters for comment.
A BTP spokesman said: 'Officers from British Transport Police recently appealed to the public for help in tracing a man who was abusive towards another man on a train.
