Police are searching for three people they say broke into Wyandanch Memorial High School Monday. Suffolk police say the break-in happened around 1 a.m. The high school's superintendent says the three broke into the high-tech music lab, but it does not appear any instruments or other items were stolen. He says the suspects ran out of the building when security guards noticed them. Police say it doesn't appear the incident is related to other recent break-ins at schools in Selden, Glen Cove and West Babylon.
