Police have arrested two boys, one 14 and the other 9, in connection with an arson fire that destroyed two vacant houses Tuesday evening in northeast Minneapolis.
Investigator Sean McKenna said the older boy was booked into the Hennepin County Juvenile Detention Center and the 9-year-old was released to the custody of his parents.
By state law, children under age 10 can't be charged with a crime.
The boys used "ordinary combustibles" to start the fire in a vacant house at 905 18 1/2 Av. NE., McKenna said. The blaze, reported at 7:20 p.m., quickly spread to an adjacent house.
Both houses, which were more than 100 years old, had been vacant for at least six months, but the 14-year-old once lived at the house where the fire started.
"He was familiar with the property," McKenna said. "This was child's play."
The fire was the 15th this year at a boarded-up or vacant house in Minneapolis. That compares with 38 reported in all of 2007 and 60 in 2006.
The fire came a day before Hennepin County and City of Minneapolis officials announced a new initiative to allocate $1.25 million to demolish boarded and vacant houses in Minneapolis.
