Greek police said Friday they have arrested a 27- year-old German woman on terrorism suspicions, dpa reported.
Officials of the police anti-terrorism unit seized the woman in Athens' district of Perissos in a development coming a day after police arrested four suspects in the ongoing crackdown against terror suspects.
"She was arrested in connection with terrorist activity," a police official told the German Press Agency dpa.
Further details were not given.
On Thursday, police arrested four people suspected of having connections with a terrorism group, just days before the start of a trial of dozens of radical anarchists.
Police said the four suspects arrested were believed to be involved in the Conspiracy of Fire Nuclei terrorist group that was behind a series of parcel bombs sent to European leaders and embassies in addition to a bomb explosion outside an Athens court house last month.
