Abilene police said six robberies have occurred from Wednesday to Sunday. Four of those robberies involved a weapon or a threat.
"It's startling quite frankly--unfortunately these things are gonna spike occasionally," police spokesman George Spindler said. "People need to understand that these are serious crimes."
For the first six months of this year, police reported a nearly 10 percent increase in violent crime.
An unidentified armed subject robbed First Bank Texas Thursday. Surveillance photographs show the suspect to be a masked Hispanic male wearing a blue top and blue jeans.
Police haven't been able to capture the man. They, however, have said they have received a few tips.
"Those leads are being looked into aggressively now, but we have not identified that person," Spindler said.
Also last week, a woman was robbed at gunpoint in the 2900 block of Pine Street. An Allsup's Convenience Store clerk in Tuscola was confronted by a gunman in the store parking lot.
While police haven't identified those suspects, either, they have made several arrests in connection to other recent armed robberies.
"We're very fortunate," Spindler said. "With the help of both good police work and good citizens being part of the solution, those people have been identified and were charged."
Caleb Collier, 23, Johnny Collier, 26, and Damon Russell, 25, were arrested in connection to an armed robbery at Radio Shack on North 1st Street Sep. 24. Each is charged with one count of aggravated robbery and posted their $50,000 bail.
Just a couple of weeks ago, 19-year-olds Christopher Pieczynski , Anthony Carrillo Jr., Eric Pack and 18-year-old Paul Valadez were arrested on several counts of aggravated robbery in connection to a string of armed robberies at three convenience stores and one smoke shop.
As of Monday, Pieczynski, Valadez and Pack are each being held in the Taylor County Jail on bond totaling $400,000 for four counts of aggravated robbery each. Carrillo is being held on bond totaling $300,000 for three counts of aggravated robbery.
"We can't do this job without the community's help so please, if you have any tips, let us know what's going on," Spindler said.
