Police arrested an 18-year-old man Thursday in connection with the murder of an American artist who was stabbed to death while jogging in a London park last month.

Scotland Yard made the arrest a few days after staging a reconstruction of events surrounding the death of 27-year-old Margaret Muller, from Falls Church, Va.

Muller died of multiple stab wounds to the back and neck after the morning attack in east London's Victoria Park on Feb. 3. She was found by other joggers and cyclists who heard her screams.

Police said they arrested the suspect shortly after 6 a.m. at his home near the park in London's Hackney district. They gave no further details, and didn't say whether the arrest was connected to Monday's reconstruction, which involved dozens of people and was the biggest in Scotland Yard's history.

Muller, who moved to Britain in 1998, studied and taught at the prestigious Slade School of Fine Art in London and had won a series of scholarships and commissions. She lived near Victoria Park.
