A teenager was accused after a train traveler sat on about 20 needles sticking out of a seat on a Melbourne service, with one who punched his ass.
Detectives accused a 16-year-old boy Fawkner of crimes including intentionally causing injury, assault with a weapon and offending crime while on bail.
Anthony Artusa received medical medicine after Tuesday's accident on a service from West Footscray to the city.  "Word of warning when traveling on @metrotrains" wrote Mr. Artusa on Twitter. "I had a nice surprise this morning when I sat on a seat with about 20 needles sticking out".
Metro Trains called the incident a "terrible act of vandalism" and said he was working with Victoria police to find the culprit using CCTV footage.
Speaking to journalists on Wednesday, Mr. Artusa said he boarded a Melbourne Loop train before 8am the day before and, after finding a free seat, he felt the multiple needles stab him to the back of his leg. [1
The Victoria Police Inspector Andrew Gustke said six other needles were found near the seat.
"It's scary and very dangerous, we see this as an isolated incident," he said.
"My warning is anyone who can think of doing something like that, you are under observation and you will be captured and we will punish you."
Insp Gustke the officers indicated were looking for a male criminal who could put the needles on the seat during the night Monday while the train was running on the Clifton Hill line before being changed on the route of the Water Gardens.
The 16-year-old is now in custody and will appear in a children's playground at a later time.
