A house in Capitol Heights that was to be renovated by volunteers Saturday was heavily damaged Friday by fire, authorities said.

That suspended plans for the Christmas in April organization to work on the house, in the 1000 block of Iago Avenue, said Mark E. Brady, spokesman for the Prince George’s County fire department.

Neighbor Ann Thompson said the house was left “totally black.”

On the last Saturday of April each year, the group improves the homes of residents including those who are low-income, physically challenged or elderly.

Earlier Friday, an 18-year-old man was taken into custody after a house fire was apparently set in the 5600 block of Woodland Drive in the Forest Heights area, Brady said.

A domestic quarrel had been reported at the house, he said.
