Squatters Rights

[propertyquest]

I have a question and comment.

My question is what are the laws to remove squatter from an owner property
The police were absolutely useless in getting squatters removed.
Police were contacted 3 times by the owner, the squatters also called.
The owner was unable to have these trespassers/squatters removed by police squatters on the property had turned on lights illegally which the owner pointed out to the police, moved in a Big Flat Screen TV, livingroom furniture a hotwater tank not yet installed, numrous Cats running around and matterss on the floor in each bedroom. There is no running water or heat in the house. The police didn't consider any of the issue including proof of ownership by the owner. What rights does the Tax paying Owner have when the police are not doing their job and the owner was given a harder time then the squatter. The squatters provided two differnt leese agreements the 1st day thery were called the leese had more white-out then typing on the paperwork stated they had been living there 3 weeks the next day because the owner allowed, per the Police Offers request they be able to stay overnight due to a toddler in the house. The Squatter still had not moved by the next evening when the owner insisted they leave the squatter called police again and provided the 2nd leese agreement stating they had been there 3 months instead of 3 weeks. When the house was purchased the house had been vancant a year or more and the house is checked on every 24/48 hours the owner lives only 5 blocks away.
The owner was asked by an police officer to let them stay 5 more days rather the remove the squatter, which will give them more valid time to do whatever they want to the property be it improve or destroy. forcing the owner to have to go through charges for eviction paperwork, court date etc. Please help what is the soluction without going throug the court system and giving these squatter more time in the property? I did find online a site that give squatter how to instructions and these squatter seem to be following the instruction listed there
