The mother of a man who allegedly doused a woman in petrol and set her alight has urged him to contact the police.
Stephen Archer, 50, has been on the run since the attempted murder on Monday - and it has emerged that his mother, Wendy, has since received a birthday card from him.
In a recording released by Greater Manchester Police, Ms Archer says: "Steve, I have got your card. I want you to know that no one is controlling me and no one is forcing me to send this message to you.
"I know you think I am covering up things but I am not. I do not want any harm to come to you. Will you please contact the police."

The 49-year-old woman who was injured in the attack, believed to be his sister, remains in a critical condition after suffering burns to 70% of her body.
Police have described Archer, from Openshaw, as a "particularly dangerous and unstable" man who was "obsessed" with petrol.
Detectives also said he may be carrying several bottles of petrol, and have warned petrol station workers to be "extra vigilant" and alert the authorities if they see him.
Superintendent Arif Nawaz said his team "will not stand down" until he is found.
"We can assure the victim, the family and the wider public that we are doing everything we can to find the person responsible and bring them to justice," he said.
"Stephen usually wears a baseball cap, carries a large rucksack and he is known to travel on a bicycle."
The public has been urged not to approach Archer, but to call police on 999 as a "matter of urgency"
