An 80-year-old woman was left in critical condition after she was set alight outside her flat in Watford, England, police said. Officers were called at 12.47pm on Monday to a communal area of a block of flats at Caractacus Cottage View. Hertfordshire Constabulary said the woman was found alight. Police said they believe some kind of liquid was sprayed on her before she was set on fire as she returned home. Detectives previously said an accelerant liquid was also poured through the letterbox of a nearby flat. A 33-year-old man was arrested on suspicion of conspiracy to commit arson with intent to endanger life. He has since been bailed with strict conditions, police said. The woman’s family said they were left in complete shock and “desperate for answers”. In a statement, they said the woman remains in hospital in a critical condition, and asked anyone with information to come forward. The family requested privacy during what they described as an “unimaginably difficult time”. Police continue to investigate the incident.
