Carlisle parents arrested after baby death
A man and a woman have been arrested in Cumbria following the death of their baby son in 2011.
The pair, aged 32 and 24, from the Harraby area of Carlisle were arrested by Cumbria Police on Friday in relation to the death.
Both were released on bail pending further inquiries.
Det Supt Mike Forrester of Cumbria Police said: "We have a duty to investigate all unexpected or suspicious deaths."
He added: "We appreciate this is a very difficult and stressful situation for this child's parents.
"Only when it is absolutely necessary and we can justify such action do we take these steps."
