A stroll down a Manhattan sidewalk proved fatal for a married father of three after he tripped on a raised and broken tree bed, according to a lawsuit.

Kanaya Manglani, 67, stumbled over the cobblestone tree bed between 1503 and 1509 Second Avenue in July 2018, and hit his head on a bus as he fell, family lawyer Salvatore Aspromonte said.

Manglani suffered “severe, protracted personal injuries” which resulted in his death eight months later on Feb. 4, his family alleges in a Manhattan Supreme Court lawsuit filed against the city.

The city had a duty to keep the sidewalk in good repair, the family charges in court papers seeking unspecified damages.

The city recently announced it would take responsibility for sidewalks damaged by trees, ending a practice of slapping home owners with fines for the damage.

“Losing a family member is tragic. We’ll review the details of the case,” Law Department spokesman Nicholas Paolucci said.
