A 33-year-old man has been charged in connection with a bomb alert at the office of East Belfast MP Naomi Long.
He is facing charges of intimidation and placing a hoax device outside the cross community Alliance Party's offices on Newtownards Road last Tuesday.
He is due to appear at Belfast Magistrates' Court tomorrow.
Ms Long has been subjected to a lengthy campaign of intimidation over her party's stance on the Union flag dispute at Belfast City Hall.
Earlier this year she was issued with a death threat by loyalist paramilitaries.
A spokesman for the Police Service of Northern Ireland said the charges may be reviewed by the Public Prosecution Service.
