Police say the thieves have hit five homes in a matter of a week, from June 6 to June 12, all of them in South Lansing.
In all cases, they took piping. In some cases, they took carpeting, air conditioning condensers, and power tools.
A red Pontiac was observed at one of the scenes, occupied by three white males. Police don't know if it's involved, but they are asking neighbors to keep a look out for homes under repair in their neighborhoods. The number to call is 483-4600.
