AUSTIN - Austin police are reporting that there was no package explosion at a Goodwill store in Texas and that an item found earlier Tuesday night was not a bomb, but rather an incendiary device, a federal law enforcement official told CBS News. A flare was included in a bunch of donated items and as a Goodwill worker was sorting through the items in the box he was apparently burned by the flare. 

Authorities believe this incident is not linked to previous package bombs that have rattled nerves in the Austin area.

Austin authorities said earlier that they were responding to another report of an explosion Tuesday night in Texas that has left at least one person injured, according to Austin-Travis County EMS (ATCEMS). The Austin area has been hit by a string of bombings since March 2 that has killed two people and wounded four others seriously.

ATCEMS wrote Tuesday that officials were on scene Brodie Lane/W Slaughter Lane. The incident occurred around 7 p.m. local time.

Apparently a male in his 30s has potentially serious, but non-life-threatening injuries. He was rushed to the St. David Medical Center, according to CBS affiliate KEYE-TV.

CBS News has learned that the explosive device was inside package and it went off at a Goodwill donation dropoff location/store.

The explosive device was left in a box at the location, CBS News' senior investigative producer Pat Milton reports. The location is about 3 miles south of a FedEx store where another bomb incident happened earlier Tuesday.

KEYE-TV reporter captured video of authorities rushing to the scene:

Andy Sevilla, editor of the Austin Statesman, joined CBSN to describe the scene and said that the exact condition of the victim isn't known yet and that police are blocking the area as they investigate.

"People were visibly shaken ... you can smell smoke in the parking lot," Sevilla said. "There are a lot of people outside trying to figure out what's going on ... if they're safe and what to expect."

Sevilla pointed out that there has been a flurry of activity over the last few days and "first responders are out here taking this very seriously."

Investigators are pursuing a suspected serial bomber in the Texas capital  area. Earlier Tuesday, they responded to a FedEx shipping center near San Antonio where a package exploded on a conveyor belt in the middle of the night and caused minor injuries to a worker. Although the latest blast did not inflict serious harm, it added to the widening fear of more strikes like those that have already killed two people and badly wounded four others.

If Tuesday evening's explosion is linked to the earlier ones, it will be the sixth one to occur this month.
