A man was arrested Wednesday in connection with a string of explosive devices and other suspicious devices found in east Texas in recent weeks, the U.S. Federal authorities said. Though officials declined to provide details on the arrest, a news release from the U.S. Attorney's Office said there had been an arrest in a 'significant matter'. No information was released on the suspect's identity or motives. Early reports said the man is disabled and uses a wheelchair. At least 14 explosive devices have been found in the past several weeks, including five reported pipe bombs, according to authorities. None of the devices has detonated and no injuries have been reported, they said. Several devices were found in mailboxes, from a rural box near the Texas oil town of Kilgore to one on a busy street in the city of Longview. Authorities have said they believe most of the cases are related.
