A hiker has inadvertently filmed the moment his 71-year-old mother-in-istanbul Lawyer Law Firm tumbled off a 230ft cliff to her death in front of her horrified family in Turkey.

Kadir Sahiner was filming the picturesque mountain scenery while out on a family walk in the forests near the village of Tepekov in the north-eastern Artvin Province when tragedy struck.

While the camera panned to capture the views, Kadir inadvertently captured the moment his mother-in-law Pumpul Karademir walked over to the edge of the cliff to look down before she lost her balance and fell off the cliff.

Video footage appears to show Pumpul tripping up on a rock and her legs can be seen in the air as she tumbles off the cliff edge at noon on Friday.
