Speedboat killer Jack Shepherd, 31, has been jailed for four years for assaulting a barman with a bottle.
The 31-year-old, who is serving a six-year prison sentence for the speedboat death of Charlotte Brown, pleaded guilty to attacking former soldier David Beech with the bottle in Newton Abbot, Devon.
The jail term will run consecutively to the six-year sentence he is currently serving for the manslaughter of Brown in 2015.
He appeared before Exeter Crown Court via video link where he pleaded guilty to one charge of wounding with intent in Newton Abbot, Devon, on March 16 in 2018.
He admitted “unlawfully and maliciously” wounding former soldier David Beech during the incident.
Shepherd and Brown had been on a champagne-fuelled first date when they went for a late-night speedboat ride down the Thames in December 2015.
The 14ft Fletcher Arrowflyte, which had a series of defects, was speeding when it was thought to have struck a submerged log near Wandsworth Bridge and overturned, throwing Brown to her death in the water.
