Where do you live? His mom isn't likely to come after your sister with a shotgun for yelling at him. If she does, call the police when she shows up. You are right, they probably will come steal the bike. That's what happened to my son and his bike and we never got it back as it was stolen off the front porch and we had no evidence although we knew the boy who took it. Lock the bike in the garage, if they do get in it's breaking and entering in addition to theft and a bit easier to prove. If you can, you can booby trap the garage to make lots of noise if anyone enters. Make it hard as you can to get to the bike quietly. Speak with the local police if you can just to let them know what's going on, it won't stop them but may help if they are successful. Tell your sister to speak to them firmly but calmly, that's more scary than yelling. Tell them she knows what they are up to and is watching them. Try to avoid conflicts/fighting it just makes things worse. Also mark the bike so it's easy to identify and prove it's your brother's.

What you do is you tell you parents. There is NOTHING you should do!! it's up to your parents to handle the situation. Bring the bike IN the house. I'm sure there's some out of the way place he can put it.

Call the police.

call police and tell them to verify if she has rightful ownership to the gun. also tell them that people are soliciting your house and there are threats of stealing a bike. dont be pus*y and call them.

Pray, God helps those in need, always.

ohh my so dangerours

you might think this is kinda long but i need help!!

well i am 14 and my brother is 16. we live in a house that is near lots of other houses. there are 4 roads that are sort of connected. we live in the third road. my brother used to be friends with like all the other children that live around. there were these three boys. one is 14 and the other two are 13. he was friends with them. (dont think its wierd that theyre younger than him because they were all different ages between 12 and 14 and there were lots of them). one of the boys, jason, who is now 13, has now got a criminal record. my brother stopped hanging round with them when he was 14 (2 years ago). so since then jason got a criminal record. it had the theme of pedophilia. (my brother would of never considered being friends with him if he knew he was like this). his mum owns a shotgun! also the other two boys (one 13 and the other 14) are trouble as well (my brother is nothing like them). my brother got a bike for his birthday and jason is threatening to my brothers riends that he will steal it. there is a lane behind us and the three boys were hanging around the garage (where we keep the bike) so my sister told them to go away. they have but they will almost definately come back. so what should we do? my sister is quite angry now and so is thinking about yelling at them and swearing and stuff. this worries me because the boy will probably tell his mum and she has a shotgun!!! PLEASE HELP!!!
