A dad jailed for 15 months for sexually touching his teenage daughter had incest porn on his phone.

The 46-year-old, who won't be named to protect his daughter's identity, appeared at Woolwich Crown Court for sentencing after pleading guilty to sexually touching her over the course of two horrific incidents.

The dad was largely absent from his family's life but reconnected with them when his daughter when she was 15-years-old, the court was told.

Described as being like a "ghost" until that point, the court heard that he used her excitement at reconnecting with him against her.

After taking her shopping he invited her to his house where he initiated sexual contact despite her attempts to keep him away, the court heard.

His Honour Judge Christopher Kinch told the defendant: "Over the course of the night what should have been a joyful event turned into a nightmare."

When she left the following morning he warned her not to say anything to their family, the court heard.

A few days later he visited their family house, going into her room where he pestered her and sexually touched her once again.

He was reported to police after people close to the her noticed a change in her behaviour.

The dad was arrested and a search of his phone revealed he had searched for incest pornography.

The man, who had no previous convictions, was given an immediate custodial sentence of 15 months in prison.

He is also banned from living in the same house as anyone aged under 16.

Judge Kinch told him he had committed the "most painful breach of trust that a child should have in their parents."
