Spurs are also gathering evidence regarding the claim that Arsenal's Bacary Sagna was spat on while injured.
While the clubs may take action against some fans, there is little prospect of action under the Football Offences Act (1991). In 2009 prosecutions were brought against Spurs fans for abusing Sol Campbell, resulting in Portsmouth Magistrates' Court issuing three-year soccer bans and fines for six supporters.
The allegedly homophobic and racist angle to those songs qualified them as harassment, though, rather than merely distressing.
Until there is a complaint to the Metropolitan Police regarding harassment, they cannot act.
Neither will there be FA charges against Tottenham or Arsenal. The FA obliges clubs to ensure their supporters refrain from "violent, threatening, obscene and provocative behaviour".
This was one of two charges of which West Ham were found guilty in January 2010, after crowd trouble marred their Carling Cup match against Millwall at Upton Park, resulting in a £15,000 ($30,000) fine. A similar charge after the latest events is thought to be unlikely.
