In England, a phone service aimed at protecting women as they walk home could be on the cards.
Their Home Office says it's received a letter from the boss of BT - proposing an emergency number be used to allow people to have their journeys tracked - triggering an alert if they don't get home.
It's in response to the public outrage over Sarah Everard's murder.
Polly Mackenzie is the director of the cross-party think tank, Demos.
"The proposal here is, in a way, replicating what millions of women do informally with their friends. I've often walked home and stayed on the line to a friend or family member, just so that you know, that somebody will know if anything bad has happened."
