Boston (AP) -- The mother of a man arrested near the Boston Marathon finish line carrying a backpack containing a rice cooker on the anniversary of the bombings says her son has a mental disorder.
Joie Edson tells The Associated Press that her son Kevin "Kayvon" Edson has bipolar disorder.
The 25-year-old was arrested Tuesday. He is scheduled to be arraigned Wednesday in Boston Municipal Court. The Suffolk district attorney's office confirmed his name.
He faces a charge of possession of a hoax device, but authorities say more charges may be added.
The man was stopped late Tuesday by an officer who saw him acting suspiciously, including walking barefoot down the middle of a street, veiled in black, in pouring rain.
Last year, two bombs made from rice cookers killed three at the marathon.
Police say they've taken a man into custody in connection with two unattended backpacks found at the Boston Marathon finish line.
Police spokesman Dave Estrada says the backpacks were discovered Tuesday evening, a year after two bombs in backpacks exploded at the end of the marathon and killed three people.
The bomb squad is checking the backpacks found Tuesday. Police have cleared the area. Trains are bypassing the nearby Copley Square station. The police department has tweeted asking people to avoid the area.
Survivors, first responders and relatives of those killed in last year's Boston Marathon bombing marked the anniversary Tuesday with tributes. Former Mayor Thomas Menino spoke at the nearby Hynes Convention Center.
Amid a throng of police and high security for the Boston Marathon, authorities are investigating two suspicious bags that were left at the race finish line Tuesday evening.
The race took place a year after bombings at the finish line killed three and injured 264.
Police said the bags were left in the area of Boylston St. and Exeter St., and the road was closed. A Massachusetts Bay Transportation Authority offcial said after the discovery, Green Line trains are not stopping at Copley Station. No other information was available.
Peter Wilson of WBZ tweeted that people have been moved away from the Boston Marathon finish line. A black backpack is seen in the tweeted photo placed in the middle of the road.
