The Echo Park Improvement Association broke the story in its EPIA newsletter: Lucha Libre in the Echo.

…right next door to the Del Mor [apartment building on Echo Park Ave.] is – whump! – a gray industrial shed that houses a ring for Lucha Libre, the Mexican-style of wrestling….Lucha Libre is a pastime of Sergio, the Del Mor’s building manager, who uses the ring to train would-be wrestlers in the sport. Sergio has even been known to hand out a few free passes to Mexican wrestling matches to tenants in the Del Mor.

Vive la lucha!
