Guns N' Roses guitarist DJ Ashba got engaged to girlfriend Nathalia Henao last week, but according to a Las Vegas publication, the way Ashba proposed has sparked a police investigation.

Fans found out about Ashba's engagement through the guitarist's Twitter account on Aug. 8. Ashba, who is also a member of Sixx: A.M., tweeted a picture of Henao wearing her engagement ring, along with the words, "She said yes!!!" Another tweet from Ashba read, "We can't thank you all enough for the beautiful love and support that you show us! much love!!"

On the day that Ashba tweeted out the good news, no information was released on exactly how the guitarist proposed. However, on Aug. 10, Ashba posted a photo (see left) of himself and Henao taking a helicopter ride via the musician's Instagram account. Ashba also described how he proposed in great detail:

That was the most incredible day of our life!! Special thx to the Las Vegas Police Dept. for the most amazing helicopter private tour over Vegas! We landed in a field at Police headquarters were I had a table set up covered in roses n a bottle of the bubble stuff for @naty_yummi8 as we walked up to the table @karikaisner slipped me the ring, and thats when I proposed! it was beautiful she didn't expect a thing, it was magical. And thanks to our good friends for helping making it all happen!! Dave and @nitaoleary @tommyoleary #AshbaFamily #RnR#blessed #shesaidyes #HolyCrapWereGettingMarried #engaged#forever #miamor #thejewelersLV

According to the Las Vegas Review-Journal, police department officials are upset with the "misuse" of the helicopter. The publication also pointed out that officer David VanBuskirk, 36, died last month during the helicopter-assisted rescue of a stranded hiker. Police Captain David O'Leary, who Ashba gave a shout out to in his Instagram message, is now under investigation along with the pilot who flew Ashba and Henao.

Stay tuned as news continues to break.
