Dutch prosecutors have allegedly dismissed multiple criminal complaints involving Maccabi Tel Aviv supporters after surveillance footage from Amsterdam’s metro system—potentially key evidence—was discovered to have been deleted due to equipment replacement and short retention policies, according to NOS.

The Public Prosecution Service (OM) confirmed it has dropped two separate investigations into violent incidents involving Maccabi supporters that took place around a match against Ajax in November last year. The incidents occurred in the metro system, where confrontations broke out between groups of supporters and counter-protesters. Footage that could have supported the allegations was reportedly not preserved, the OM said Sunday.

Transport company GVB acknowledged that the video recordings were lost because recording devices were replaced on November 12—five days after the unrest in the city. "Unfortunately, this necessary replacement, combined with a limited retention period, resulted in the footage no longer being available," a GVB spokesperson said. The company added that although the standard retention period is one week, recordings are sometimes saved for less time.
