Hello,

My father is working for CAT in mandi House office. This house: 82 F, DIZ area, sector 4, type 2, baba kharak singh marg, new delhi -110001 is alloted to him.
Here the roof is heavily damaged and there is no proper action taken by JE. Yesterday, our bathroom roof fell down and my father was taking bath at that time. He is heavily injured and got 3 stitches in his back side of the head.
I have proper proof and photos of damaged roof and my father as well who got injured because of that. I need promt action to be taken against such misconduct. I am also filling a police complaint against this.
I am requesting the authority to take necessary action this.
