Abetment A person abets the doing of a thing when he or she
(a) instigates any person to do that thing;
(b) engages with one or more other person or persons in any
conspiracy for the doing of that thing, if an act or illegal
omission takes place in pursuance of that conspiracy, and in order
to the doing of that thing; or
(c) intentionally aids, by any act or illegal omission, the doing
of that thing.
Whoever abets any offence shall, if the act abetted is committed in
consequence of the abetment, and no express provision is made by
the Penal Code for the punishment of such abetment, be punished
with the punishment provided for the offence.
TS, might want to look at this, as well as on Vandalism:
Mischief Mischief is committed by a person who, with intent to
cause, or knowing that he or she is likely to cause, wrongful loss
or damage to the public or any person, causes the destruction of
any property, or any such change in any property, or in the
situation thereof, as destroys or diminishes its value or utility,
or affects it injuriously. For instance, A commits mischief if he
voluntarily throws into a river a ring belonging to Z, with the
intention of thereby causing wrongful loss to Z.[103] The penalty
for mischief is imprisonment of up to three months, or a fine, or
both.
