An explosion that injured two men in southwest Austin on Sunday night--the fourth explosion this month--was set off by a tripwire.

In a press conference on Monday morning, Austin Police Chief Brian Manley said though the method of detonation was different, this latest bomb has similarities to three previous explosions in the city that left two dead and two injured.

It happened in the 4800 block of Dawn Song Drive near Mopac and 290 around 8:45 p.m. Sunday.

Austin Police are asking anyone in the Travis Country neighborhood with security cameras to notify the department right away in hopes of finding any information on the suspect or suspects.

The area is now safe, police say, but the neighborhood will remain locked down until 2 p.m.

Manley says investigators are "working under the belief" that the explosives are similar, but Sunday's bomb was on the side of the road, not on a front porch.

Speaking to "Good Morning America," Manley says the most recent bomb showed "different level of skill."

The explosion injured two men, ages 22 and 23, who were walking in a grassy area along a roadway.

Austin Mayor Steve Adler says both men hurt in the latest bombing are white, unlike the minority victims of the three previous attacks.

On Sunday, Chief Manley announced a new combined reward of $115,000 for information leading to the arrest of whoever is responsible for those explosions. Manley also urged the person or persons to come forward.

Hundreds of federal agents with the FBI and ATF are assiting Austin Police in the investigation, as well as bomb techs from all over Texas and the United States.

If you have any information, you are asked to call APD at 512-974-5210.
