Police have arrested a man who they allege raped his eight-month-old daughter and took pictures which he sold on Australian porn websites.

The 27-year-old is from town of Berdychiv in northern Ukraine's Zhytomyr Oblast region, and reportedly believed he would never be identified because he was selling the images on Australian porn websites.

The pervert father raped the infant while taking pictures on his smartphone, according to police.

He was arrested in a dramatic early morning raid at his home while his family were still sleeping, and pictures of his arrest were then released online by police.

One of the pictures shows the suspect dressed only in his underwear. Another one shows a woman and a child.

Vitaly Chubaevsky, deputy chief of the Ukrainian national cyber police department, said: 'The man was raping his child when the mother was away or was working in the garden.'

The mother only learned about what was happening with her daughter from the police and has became the most important witness in the case after she was horrified at what her husband had done, reports said.

The 27-year-old father is a former soldier, who was unable to work properly after he was injured in 2014 in Eastern Ukraine.

A police spokesperson said: 'The man's smartphone is full of evidence. We found it hidden in the baby's room among her toys.'

The pictures were circulated on Australian and Russian porn websites and were noticed by Australian cyber police, who liaised with their Ukrainian colleagues.

Ukrainian police confiscated the suspect's smartphone along with his computer, which were sent for examination.

Online commentators have reacted with outrage.

'I thought I had seen everything, but I was wrong,' said one, while another declared that the man should 'Rot in prison.'

The suspect faces 15 years behind bars if found guilty of raping his baby daughter.
