The explosive device was placed in the front yard of the house and three houses and two cars were damaged when it exploded, police said.
The Thursday attack happened outside the house of prosecutor Paraskevi Kalaitzi, best known in Greece for trying the case of an organized crime ring convicted of several offenses, including the murder of a businessman and the kidnapping of a Greek shipowner.
The shipowner, Periklis Panagopoulos, was kidnapped in January 2009 and held for eight days until his family paid a ransom.
Several small makeshift bombs have exploded in Greece in recent years as the country struggles through harsh austerity measures imposed by foreign lenders. Gas canisters are often left at tax offices and politicians΄ offices.
