[Deadpool movie] How does Colossus know about Deadpool?

Since he's an artificial mutant, is he detectable by Cerebro? And when did Colossus learn about Deadpool's existence? Although not in chronological order, the movie shows pretty much everything that happened after Wade escaped the workshop, how do they know about each other?

I assumed it's because Deadpool is pretty much the opposite of discreet. When word gets out that a dude in a red suit with crazy healing powers is slicing and dicing people in broad daylight all over the place, the X-Men probably find out very quickly.
