You don't say whether this tom is feral or maybe a pet? If you think he maybe a pet you could try putting a collar on with a message to his 'owners'. You could try informing them of the damage he is doing & offer help with getting him neutered. PDSA or Cats Protection will help.
If you know he's feral the cats protection should be very helpful about capture, neutering & re-homing. They, like me, believe that entire tom cats are contributing to the over population of unwanted/stray cats & at risk of catching and spreading (to domestic population too!) STDs or becoming a road casualty/fatality because they have the urge to roam. If you have had personal experience of how devastating cat flu or feline leukemia virus can be you will understand. Even 'feral' cats deserve a safe place to live, regular food & basic healthcare. Good luck.
