PSNI are appealing for witnesses following an attack at a home in Poleglass today.
Windows of the house in Colinbrook Close were smashed, leaving the home owner, 57-year-old Joseph McCann, badly shaken.
Sean McCann told Belfast Live that his father is only recently out of hospital.
He said: "He doesn't leave the house, apart from attending the hospital. He suffers from brain damage.
"Me and my brother were out. We look after him as his full-time carers. We got a phone call saying that there was windows smashed. We rushed over and that's what we saw.
"My daddy has to leave this house. He thought that he was getting shot at and back in The Troubles. He thought it was a machine gun coming in the window. He wants to leave this earth."
