The Crown Prosecution Service has been asked to review evidence into the coronavirus-related death of a train ticket collector who was allegedly spat at.
British Transport Police (BTP) said the review into Belly Mujinga's death is in "recognition of wider public interest" after more than a million people signed an online petition in support of seeking justice for her family.
The 47-year-old rail worker died from COVID-19 in April, a few weeks after the incident at London's Victoria station, leaving a widower and an 11-year-old daughter.
BTP said they interviewed a 57-year-old man but said the incident did not lead to the worker's death and decided not to refer the case to the CPS.
On Friday, BTP said it had invited the CPS to conduct an independent review of the available evidence, and whether there were any further lines of inquiry.
"We can assure the public that we have comprehensively reviewed all the available evidence and have not identified any offences or behaviour that meets the threshold for prosecution," BTP said in a statement.
Ms Mujinga's husband, Lusamba, thanked those who have signed the petition and said the family had been on a "roller-coaster of emotions".
