La Clery resident, Ricky Raynold, was taking a break from some painting at his home when he said he noticed smoke coming from his neighbour’s house.
Along with the smoke, he witnessed a frantic adult and two children at a window of the house which had become engulfed in flames.
Raynold told the Times he rushed to the rescue, helping the three away from the danger zone.
He recalled that at one point he had to rush back to his home to get a ladder to complete his mission.
The four bedroom residence in one of the La Clery lanes past the Vide Bouteille Secondary School, belonged to the Black family which has occupied the dwelling for decades.
One member of the family, Davia Black, told the Times that her Aunt, her one year old nephew and another young relative were at home at the time of the blaze.
The Aunt is reported to have been watching television when the screen went black, and the house became engulfed in smoke.
Neighbours told the Times that the Saint Lucia Fire Service arrived on the scene with one fire truck and an ambulance, but all the contents of the house were destroyed.
Seven persons are now homeless as a result of the fire which occurred at about 10:30 AM.
