I had a similar experience in 2020 in Bellandur. Some monkeys entered the society.
At that time, we used to order food from Milkbasket. They would come and leave the goods at 6 AM near the doorstep. One day, a monkey came and tore up all the packets.
In the second incident, our window locks weren't working, and the monkeys kind of figured it out and entered our house.
Finally, after weeks, the society management took action. Apparently, there are professional monkey-catching services in Bangalore, but they are costly, charging 20-30k per day.
