An 80-year-old woman is in hospital after being set on fire outside her flat, police have said.
Brenda Raymond, who is in a critical condition, was found alight in a communal area of a block of flats in Watford, just after 12.45pm on Monday.
Detectives believe a liquid was sprayed on her before she was ignited as she returned home.
The police have publicly named the victim in an attempt to trace whoever was behind the violence.
