I've heard about this, but it's very odd. At least to me.
On the northwestern borders of DDS (with Afar and Oromia), liyuu police have for the most part only engaged when it involves Somalis facing non-Somalis militias and regional forces. And the conflict doesn't involve two communities/clans on each side. Such as the case on the Afar borders, with Somali locals vs. Afar militants. Rather than Somali vs. Afar locals.
In our side of the region, Liyuu have largely stayed out (after Cagjar took over), because there are two communities at odd with each other. Even though you have militias from Oromia involved, Cagjar have abstained to avoid being accused of taking a side. Liyuu have therefore been out of the picture despite *armed people and arsenal* crossing the border into our region whenever there are fightings.
So, I don't understand why Liyuu would engage in this area, which is the same region as mine and border Oromia as well.
