Ipswich local Damian Jackwitz has recounted the moment he tried to kick in a door and break metal bars on a window, while attempting to save a teenager trapped in a house fire.
Mr Jackwitz and his neighbours sprung into action early yesterday morning, while the home in Booval went up in flames.
A 14-year-old boy remains in a critical condition and another serious, after escaping the blaze.
Four other teens are stable after inhaling smoke.
Those who came to help are being hailed as heroes.
