A 63-year-old man has been arrested in Kavala, northeastern Greece, on suspicion of abusing the nine-year-old granddaughter of his Bulgarian wife.
Police said the child approached them with the help of her aunt and accused the unnamed man of having assaulted her since the age of six.
The girl lives in Bulgaria but often visits her grandmother in the area of Lydia, near Kavala, police said.
The 63-year-old was arrested on Thursday, when a search of his home led to printed pornographic material being discovered. Police did not give any more details.
