A man accused of murdering a father travelling on a train with his teenage son is due to appear in court.
Darren Shane Pencille, 35, will appear before magistrates on Monday accused over the death of 51-year-old Lee Pomeroy, British Transport Police said.
Officers said he was further charged with possessing an offensive weapon, while 27-year-old Chelsea Mitchell was also charged yesterday with assisting an offender.
The pair will appear at Staines Magistrates' Court.
Mr Pomeroy, who lived in Guildford and owned an IT firm, was travelling to London with his 14-year-old son on Friday afternoon when he was attacked.
A manhunt led detectives to a flat in Willbury Road on Saturday morning and they made two arrests.
The father, who would have celebrated his 52nd birthday on Saturday, was described by his family as "an honourable man and would always help somebody who was in trouble".
Mr Pomeroy and his son boarded the 12.58pm train service between Guildford and London Waterloo at London Road station on Friday afternoon.
Police believe a brief row broke out leading to Mr Pomeroy's death.
