BOBs battled hard to secure the draw - "their best performance of the season, according to boss Paul Shamplina - but Camden nicked it a minute into injury team as BOBs failed to close down a shot from the edge of the area that the unfortunate Lussman deflected into his own net.
Camden gaffer Nick Kagan told JC Sport: "We survived a torrential downpour and some robust challenges to steal a deserved win in the closing minutes.
"We totally dominated the game - our possession play is excellent to watch at times and we are conceding very few chances.
"However, we should have been out of sight in this game, as well as last week, and yet both times we had to really fight for points. We must get better at killing games off.
"We stay top and now have a testing cup tie away at Harmen before a must win league fixture against NLR B. Exciting times for the Graphites."
Brixton boss Paul Shamplina told JC Sport: "It was a great battling performance against the best team we have played in the league.
"I'm gutted we could not see out the game at 1-1. That would've felt like a win, but tiredness and poor ball retention cost us in the end.
"I can't criticise the effort, which was first-class, but we have to start picking up points, or we are going to get routed."
