Daniel Radcliff breaks down in tears on reading his great-grandfather's suicide note

Daniel Radcliffe breaks down in tears on BBC’s Who Do You Think You Are? after reading a suicide note written by his great-grandfather, the Time reports.

The Harry Potter actor discovered the family tragedy while participating in the BBC series.

In 1936, his great-grandfather Louis Gershon, who ran the family jewellery business in London’s Hatton Garden, was deeply affected by a robbery of goods amounting to approximately £3,000

The news made headlines with one story featuring a photograph showing Gershon collapsing upon hearing about the theft.

Fearing that the insurance company wouldn’t pay out, Gershon died by suicide after writing the note that finds its way into Radcliffe’s hands during the show’s episode.

“You want to just reach into the past and go, ‘Whatever you’re going through, you have so much to offer the people who are around you and they still would all have loved you’”, an emotional reportedly Daniel Radcliffe says.

Who Do You Think You Are? returns to BBC One on Tuesday. This year’s participants include Kate Winslet, Paul Merton and Bond star Naomie Harris.
