A Bognor man has been charged with arson with intent to endanger life.
He was arrested after a fire broke out in a house in Collyer Avenue yesterday afternoon, police say.
Dawid Stroinski, 31. was arrested shortly after the fire.
The charge was later amended to arson being reckless as to whether the life would be endangered.
A spokesman for the fire service said they received multiple calls to the house and sent two fire engines at 12.45pm.
Once there, firefighters were able to contain the fire to the first floor bedroom where it started.
Paramedics assessed two people at the scene, the fire spokesman said.
The fire service is conducting an investigation into the blaze along with Sussex Police.
Mr Stroinski, also of Collyer Avenue, remains in custody and will appear in court tomorrow.
