SAN ANTONIO - A warning for the city’s south side Wednesday morning, the San Antonio Police Department Bomb Squad is going through a training exercise in that area.

That means there will be several loud detonations as they practice how to handle bombs.

The SAPD training academy is located in the 12200 block of Southeast Loop 410. Training will be going on from 10 a.m. to noon.

So, if you hear a rumble there's likely no cause for concern.
