Police were called to a Coppell apartment complex for a suspicious device that turned out to be a city mosquito trap.
An apartment manager reported a suspicious device in a common area of the complex near Sandy Lake and Moore roads on Monday evening.
Police later said the device was a mosquito trap placed by the city health department as part of its efforts to monitor West Nile virus activity. Authorities said the device was in a spot typically used by the city to combat West Nile virus but that the apartment manager was not familiar with the mosquito trap.
Some apartments near the mosquito trap were evacuated as a precaution while police investigated.
