Police not intervening to protect Cargo run from pirates

[tropicalpioneer]

Observed behaviour

Upon arrival in the destination system, the pirate ship engages my ship and I received a Comm message about the fired shots and sending for help.
No support is approaching, the police keeps at a 15km distance even if I try to get closer (looks like it keeps an escort distance).

I suspect there is something to be fixed, as well because when I managed to get the chasing pirate closer to the police, the police shot some fire at the pirate, but stopped when me and pirate got back at >6-7 km distance.

Expected behaviour

Police should approach and engage the enemy until destroyed.
