A man has been arrested in Thessaloniki after neighbors saw him scaling a block of flats to burgle his grandmother’s apartment and called police, authorities said Friday.

Police said the 34-year-old man is suspected of having taken a total €500 from his grandmother’s second-floor flat after climbing up the side of the building. He faces charges of theft.

The alleged burglary took place Thursday in the northern port city’s district of Menemeni. The elderly woman was not at home at the time.
