The alleged blast from a bombing package again rocked Austin, the United States, and wounded two people on Sunday (18/3).
"The Austin Police Department (APD) responded to a bomb blast call at 4800 Dawn Song Dr. blocks. Two male patients were rushed with unknown injuries," the APD statement said on their official Twitter account.
Sources told ABC News reported that the Federal Bureau of Investigation (FBI) and the Bureau of Alcohol, Tobacco, Firearms, and Explosives also responded to the incident.
Until now, there is no known cause and source of the explosion in Austin.
The incident came just a week after police claimed that the three-packet bomb incident that exploded in the past 10 days was linked.
This series of incidents started on March 2, when Anthony House died of severe injuries after opening a package that appeared to contain a bomb in front of his house.
Ten days later, a 17-year-old teenager named Draylen Mason was killed when he opened a package left in front of his house.
A few hours later, a 75-year-old woman was injured after opening a strange package on her porch.
Police also offer rewards of US $ 100 thousand for residents who have information about the perpetrators of the series of bomb packages.
This week's event itself happened shortly after the police raised the rewards for citizens who have information from the US $ 100 thousand to the US $ 115 thousand.
