A house fire early Friday in Oxford, Massachusetts, 

injured five people, including a police officer.

When the fire at 45 Leicester  St. started  at 12:45 a.m., 

four family members were inside.

A mother and her two teenage daughters were able to exit  the burning house after smelling smoke.

A police officer was injured while attempting  to assist the victim, 

who had second- and third-degree burns.

A 30-year-old man was imprisoned  inside the house and jumped from  the second flor.

Officials said the fire grew to three  alarms and entirely destroyed 

the house. The cause of the fire is being investigated.
