A man is dead after allegedly blowing himself up as police officers approached him Wednesday night.

What we know:

Officers were initially dispatched to a domestic violence situation along 9th Street Southeast in Puyallup around 4 p.m.

Police said a 46-year-old man forced his way into his ex-girlfriend's apartment before tackling her to the ground and punching her in the head. The woman called 911 and was later treated at the scene for her injuries.

It's currently unknown what type of explosive device was used or if any officers suffered injuries.
