A father who killed his baby daughter before trying to murder a little boy was jailed for 12 years today.

Ian Ruddock, 34, from Shawlands, was sentenced at the High Court in Glasgow for killing his five-week-old daughter Olivia.

The financial advisor, who continues to deny his guilt, was told by judge Lord Bannatyne that the killing of was "a gross breach of trust."

As the sentence was imposed members of Ruddock's family sat weeping in the public benches.

He showed no emotion as he was led away to begin his sentence.

The court heard that on various occasions between January and March 2011, Ruddock repeatedly shook his daughter, causing her to suffer extensive rib and head injuries.

Foul play was not suspected when she died at Yorkhill Hospital on March 6 2011 and Ruddock went on to carry out attacks another child at an address in Glasgow in 2013.

The baby boy suffered a fractured skull and fractured ribs.

He was told by the judge: "You committed both these offences when both children were babies.

"It is difficult to think of more a vulnerable victim than a baby."

Detective Chief Inspector Maxine Martin, who led the investigation, said: "Olivia was a beautiful five-week old baby.

"It’s difficult to understand how anyone could harm a defenceless child, let alone her father, who should have been there to protect her.

"Investigations of this nature are extremely distressing and it can be upsetting to hear and read about.

"This was a particularly difficult case to work on due to the passage of time, the ages of the children involved and because of the complexity of the medical evidence.

"I would personally like to thank the detectives from the Major Investigation Team and from the Greater Glasgow police division who worked tirelessly and professionally to investigate the circumstances surrounding Olivia’s death and the attempted murder of the other child."

 Ruddock went on trial accused of murdering five-week-old Olivia at his home in Clarkston, East Renfrewshire, in 2011.

He was cleared of murder, but a jury found him guilty of a reduced charge of killing Olivia.

Defence QC Donald Findlay said: "Mr Ruddock respects the verdict of the jury, but he does not accept it.

"The man's position is that he did not do these things."
