Syntagma, Panepistimio and Evangelismos metro stations in central Athens will close at 10 a.m. on Friday on police orders.

The move comes as a security measure in response to a scheduled rally to be held in front of Parliament to commemorate the December 6, 2008 fatal shooting of high school student Alexandros Grigoropoulos by a police officer.

The stations will be reopened once crowds disperse.
