Multiple M-type explosive devices, which are classified as illegal on the ATF’s webpage, were located within the van, according to Fox 29. Law enforcement said the illicit munitions were similar to those used by rioters to bust into ATM machines, the local outlet reported.

Unrest has surged in Philadelphia after Wallace was shot and killed by police following a call that a man was armed with a knife, according to NBC Philadelphia. Officers repeatedly instructed the man to drop his blade before shots rang out, the outlet reported.
