Marie Trintignant had been filming in Lithuania
The French rock star accused of fatally beating actress Marie Trintignant was not told of her death until three days after she died from her injuries, his lawyer has said.
Bertrand Cantat, lead singer with Noir Desir, is being detained by police in Lithuania on suspicion of attacking her following a row.
Ms Trintignant, 41, daughter of French film veteran Jean-Louis Trintignant, died on Friday after five days in a coma.
Mr Cantat's lawyer, Leonas Papirtis, said his client had not been told about her death earlier because he was suicidal and too unstable to cope with the news.
He "took it very, very badly", Mr Papirtis said.
He said Mr Cantat had talked about killing himself. "How could I tell him after he told me he wanted to die?" the lawyer said.
Mr Cantat denies attacking the actress. No charges have been filed.
Ms Trintignant had been taken to hospital in the Lithuanian capital Vilnius, where she was filming a TV movie about French author Sidonie-Gabrielle Colette.
She was flown from Lithuania to France, where she was kept alive for several days on a life-support machine.
An autopsy showed she died from repeated blows to the head.
Officials are expected to take at least two weeks before deciding on any possible charges against Mr Cantat.
