Is there a lot of crime in Colombo?

"Colombo is generally considered to be a safe city, however, there is still some crime present. Petty theft, such as pickpocketing and bag snatching, is the most common type of crime in the city. Violent crime is relatively rare, but it does occur. In addition, there have been reports of scams targeting tourists, so it is important to be aware of your surroundings," remarked another expat in Colombo, Sri Lanka.
