Oscar-winning Irish musician Glen Hansard has died in a motorbike crash in Dublin.

Hansard, 56, was the frontman for rock group The Frames and also featured in The Commitments.

He won an Academy Award for Best Original Song for Falling Slowly in 2008 which he wrote for the low-budget film Once.

Hansard was born in Dublin in 1970 and busked on its streets before landing the role of Outspan Foster in The Commitments.

Police are appealing for witnesses following the single-vehicle crash, which happened on Lower Road in Lucan, west of Dublin.

It was reported to the emergency services shortly before 04:30 local time.

Hansard was also one half of the rock duo The Swell Season, and released solo albums including Didn't He Ramble, which was nominated for a Grammy for Best Folk Album in 2016.

He was the father of a three-year-old boy.

Taoiseach (Irish prime minister) Micheál Martin tweeted that he was "deeply saddened to learn of the passing of Glen Hansard.

He described him as a "talented musician and actor who made a significant contribution to Ireland's cultural landscape over many years.

"My sincere sympathies to his family, friends, and fans."

In a statement, ATC Management, which represented Hansard, said: "With broken hearts we announce the passing of Glen Hansard who passed away, in the early hours of this morning, following a road traffic accident in Dublin.

"Glen's family is deeply shocked and heartbroken by this tragic loss and respectfully requests privacy at this extremely difficult time.

"The family is grateful for the support they have received and wishes to thank the emergency services who attended the scene."

Hansard starred opposite Czech musician Markéta Irglová in 2007's Once.

The pair played two musicians who meet in Dublin and form a creative partnership, performing songs they write together as The Swell Season.

The film won the World Cinema Audience Award at the Sundance Film Festival.

A Broadway adaptation of the film, featuring Hansard and Irglová's songs, later won eight Tony Awards, including Best Musical.
