Escort business rivalry led to fake 911 calls, say police

Calgary police have arrested an Ontario man accused of making fake emergency calls in an attempt to curb the competition in the escort business.

Police said Monday they spent nearly a year investigating emergency calls claiming that distraught women were being held against their will, either at gunpoint or knifepoint.

“It is alleged two individuals were responsible for numerous calls to police in an attempt to reveal and disrupt competition in the escort business. These same individuals are also believed responsible for extorting escorts by calling or threatening to call police if the women refused to work for the two accused,” they said in a news release.

A 29-year-old man from Ontario has been charged with two counts of extortion and four counts of public mischief. He is in custody and is set to appear in a Calgary court on Monday.

A countrywide warrant has been issued for a second person, Rong Zhang, described as a 37-year-old woman with black hair and brown eyes.
