Authorities say a man taken into custody near the Boston Marathon finish line carrying a backpack containing a rice cooker is scheduled to appear in court.
The Suffolk district attorney's office says the 25-year-old man from Wakefield is expected to be arraigned Wednesday in Boston Municipal Court. Officials have not identified him.
The man faces a charge of possession of a hoax device, but authorities say more charges may be added.
The man was stopped by an officer Tuesday, the anniversary of the bombings, after he was spotted walking down the middle of a street, barefoot and shrouded in black, in pouring rain.
The backpack was destroyed.
A second suspicious backpack was determined to have been left behind by a media outlet and was not a danger.
