Federal agents have arrested the ex-husband of the woman who received a bomb via FedEx on Sunday.
The ex-husband of the Colleyville woman who received a bomb in a FedEx box was arrested late Wednesday and booked into the Tarrant County jail on federal charges.
Investigators arrived at the north Fort Worth home of 51-year-old real estate broker David Barouch, the ex-husband of the Colleyville woman who received the bomb Wednesday morning.
Agents searched the upscale house on the 5200 block of Selago Drive throughout the day while Barouch was detained in a police car and said they found evidence linking him to the package.
Barouch had nothing to say as he arrived at the Tarrant County jail.
"I'd like to point out that we take this crime very seriously in our community," said Colleyville police chief Steve Dye. "We expended all resources toward the effort."
Shortly before 4 p.m., agents arrested Barouch on federal charges of manufacture and possession of a destructive device.
"This was a remarkably quick arrest," said Dye. "I hope this sends a message that it won't be tolerated."
Officials have not said what led them to search Barouch's home or what evidence they found. The Bureau of Alcohol, Tobacco and Firearms said only that they were looking for any evidence related to the case, including bomb making materials.
Agent Tom Crowley with the Bureau of Alcohol, Tobacco and Firearms, said the home search was a result of an extensive, non-stop, three-day investigation by the bureau and that great caution was taken during the search due to the potentially explosive nature of the evidence.
"Because of the nature of the investigation, we were taking the utmost precaution when we were executing the search warrant just for safety," said Crowley. "We had a large presence. We had the special response team from ATF along with ATF explosive agents."
On Sunday, Barouch's ex-wife discovered a package on the front doorstep of her home on the 1000 block of Dogwood Court near Colleyville Middle School . Thinking the package looked suspicious, she called authorities who informed her that it was a bomb.
On Sunday, a Northeast Fire Department Association Bomb Squad used a water cannon to disarm the bomb, described by officials from the ATF as "a serious bomb that could have caused some serious harm."
