Narrative: While on descent into ZZZ on the ZZZZZ arrival we experienced a BLD 1 LEAK Master Warning with associated EICAS and red inscription messages. The FO (First Officer) proceeded to run the QRH; while I asked for immediate vectors to ZZZ along with a descent to exit IMC and icing conditions. ATC granted the descent; as well as direct ZZZ. The bleed leak warning was still occurring while the FO waited the requisite 3 minutes as per the QRH. This prompted me to [receive priority] as the eventual end of the QRH procedure is to secure the engine should the leak not extinguish. As we descended out of icing conditions; the BLD LEAK message extinguished; prompting no further action from the QRH. At this time I notified the FA (Flight Attendant) with a TEST briefing as to the nature of our [situation]; that the immediate threat had passed and we would be landing normally. I also made a PA to the passengers to inform them that they may see ARFF (Airport Rescue and Fire Fighting) vehicles around the aircraft on landing. We continued to a normal landing on XXL in ZZZ and taxied to the gate with no further assistance required.Master Warning bell with associated EICAS and red inscription messages.Unknown problem in bleed system caused a BLD 1 LEAK Master Warning. Aircraft had been written up 3 days prior for same issue with associated maintenance entry clearing the write up.QRH ran; ATC advised to clear icing conditions; proceeded to normal landing in ZZZ.Possibly more in-depth look at bleed system whenever a leak detection warning occurs beyond ops check good.


Second narrative: On the ZZZZZ arrival into ZZZ we descended into a cloud layer and encountered icing conditions. Within 30 seconds of the anti-ice system being turned on we received a 'Bleed 1 Leak' EICAS message. As Pilot Monitoring; I ran the respective QRH associated with that message. Still being in icing conditions we decided it would be best if we advised ATC to gain priority and also since we did not know how thick the icing cloud layer was. Upon waiting the 3 minutes as stated by the QRH we exited the icing conditions and within 30 seconds the bleed leak message and inscription went away thus ending the QRH procedure. We continued to ZZZ; landed and taxied to the gate normally.


Synopsis: EMB-145 flight crew reported a BLEED 1 LEAK Master Warning on descent into IMC icing conditions and after descending out of icing; the warning discontinued.
