What is limit to pressing charges against four men for harassment in Pennsylvania were waiting for the report?

Three days ago my boyfriend was collecting scrap metal to bring to the junkyard he has permission from many places and he never goes on someone else's property without asking them first. he has a baby carriage to carry everything in and was walking past a dumpster on the street with a piece of aluminum hanging out of it he grabbed it, four men who were working on a house there started attacking him kicking our baby carriage and hitting it with a hammer, the others were smacking and kicking my boyfriend calling him names. when he got home he called the authorities and they came out my boyfriend did not fight back with them nor use any inappropriate language like them, but because my boyfriend had to go to the junkyard and three hours later called on them the officer told us he was going to fill out paperwork with the four men's information to bring to the magistrate's office however the officer didn't sign his name on the paper. my boyfriend went down there today they told him to come back on monday and the magistrate's office knows were waiting on the police report, but monday will be six days after the incident won't that be too long too press charges against them? the one man drove past our apartment and gave him the finger plus he keeps driving past my boyfriend informed them he's pressing charges against them. they told him it will never happen and kept their confidence monday he's going to the police station and picking up the police report because the officer who came out that day will be working and is gonna sign it
