Lawrence police arrested two people early Tuesday morning after two separate incidents, one in west Lawrence and one downtown.

Kim Murphree, a police spokeswoman, said police were called just before 3 a.m. to the 2500 block of Morningside Drive about a domestic disturbance after an argument became physical. Police arrested a 30-year-old woman on an aggravated battery charge after she was accused of using a chain as a weapon.

The victim was treated at the scene for bruises and laceration, Murphree said.

In the other incident, police arrested a 36-year-old Kansas City, Mo., man on an aggravated assault charge around 5:20 a.m. in the 1000 block of Massachusetts Street after he was accused of speaking aggressively to a woman in the area and holding a large tree branch in a threatening manner, Murphree said.

The woman told police she was approached by the man as she was walking to work. When a vehicle passed by she saw the man turn his head and she ran to the building where she was employed to call police.

The Journal-World generally does not identify suspects unless they are formally charged.
