A late-night apartment fire in Plano sent one man to the hospital. Police believe the fire was intentionally set and have a person of interest in custody.

The fire started around midnight at the Villas at Chase Oaks apartments, located off Legacy Drive just west of Central Expressway.

First responders rescued a man from a second-story balcony after residents heard him yelling for help. Paramedics took the man to the hospital with minor injuries, and no one else was hurt.

A roof collapsed onto firefighters during the incident, but none of them were injured, officials said. Officials say 10 units inside the building are uninhabitable because of the damage.

A fire department spokesperson said officials believe the fire was arson. Police have one person in custody as they investigate.
