Noise from a helicopter hovering over Toronto's west end raised queries on Twitter last night, until Toronto police weighed in with an answer. 

Tweets began to appear after 11 p.m. Wednesday, with many wondering why the helicopter was hovering in place over Little Italy. 

Some said the noise was keeping them awake.

While some found the helicopter's presence unsettling, others were just annoyed by the noise. According to some Twitter reports, the helicopter hovered in place for more than an hour.

Finally Toronto police weighed in, saying the helicopter was "waiting for approach to Pearson. All in order."

Not everyone was happy with this explanation.
