Updated 4:20 p.m.: Metro Transit Police had not made any arrests Thursday afternoon in the case of riders releasing pepper spray on a Blue Line train near L’Enfant Plaza.

But Metro spokesman Dan Stessel said Metro police are looking for three teens: a black female with gold hair who is wearing a pink shirt, a black female with a black shirt and tan pants, and a black male with a high-top fade hair cut and royal blue jacket.
