Neeson nephew 'in critical condition'

Liam Neeson's nephew has reportedly suffered a "serious head injury".

The 'Taken 2' star, who was left devastated after his actress wife Natasha Richardson died from a brain injury following a skiing accident in Montreal, Canada in March 2009, has been in contact with his family since learning his sister Bernadette Sexton's son, Ronan Sexton, is in a "critical condition" in hospital.
